can we get a detailed example of this please?

It's mentioned in the thread that level 45 does not work for that. Level 45 is 100273, not 100237. [[User:Sheep|Sheep]] 16:42, 21 Feb 2005 (UTC)

Nevermind the previous message, I figured it out myself. [[User:Sheep|Sheep]] 18:09, 21 Feb 2005 (UTC)

== Simplify the formulas ==

<pre>
Was that copied from matlab or something? It can be simplified...

((0.814 - 0.02*(((n - 69) / 3) - (((n - 69) / 3) modulo 1)) - ep(((n - 69) modulo 3))(n^3)

((0.814 - 0.02*(((n - 69) / 3) - float_part((n - 69) / 3) ) - ep(((n - 69) modulo 3))(n^3)
((0.814 - 0.02*( int((n - 69) / 3) ) - ep(((n - 69) modulo 3))(n^3)
((0.814 - 0.02*( int(n/3 - 23) ) - ep(((n - 69) modulo 3))(n^3)
((0.814 + 0.46 - 0.02*( int(n/3) ) - ep(((n - 69) modulo 3))(n^3)

int(  (  1.274 - 0.02*(int(n/3)) - ep(n%3)  ) * (n^3)  )
That would be easier to read.
</pre>

<pre>2*(1 - 0.01n)*(n3)
= int( 2n3 - 0.02n4 )</pre>

<pre>(  1 - ((n - 50)*0.01)  ) * (n^3)
= int( 1.5n3 - 0.01n4 )</pre>

<pre>(1.6 - 0.01n) * (n3)
= int( 1.6n3 - 0.01n4 )</pre>

I really want to avoid using expressions that are not standard math notation. I don't even know if there's a way to represent some integer rounding using standard math notation, just some pseudo-code, that's why I stuck mod 1 subtraction in there. My plan was to simplify/clean it up once TeX was implemented on bulbapedia.

In the meanwhile you can simplify them. Just keep "mod" or "modulo" instead of "%" and avoid "int()." [[User:Sheep|Sheep]] 20:20, 1 Mar 2005 (UTC)


The big problem is that when I first read that I got confused. No person that would bother to understand that formula wouldn't know how to program anyways, to represent that rounding you use ||x|| I think, maximum integer, unless I got the symbol wrong, long time I don't touch math.
I'll leave that formula but also add the simplification for anyone that wants someting simplier to read.
I will also simplify your standard math formulas, but won't add the ||x|| because I am not sure if its the right symbol, those - 69 can be taken out of modulo since they will be equal to zero.
[[User:Qgpr|Qgpr]] 20:03, 5 Mar 2005 (GMT-5)

: |x| is modul'''us''' - gives the absolute value of function, i.e. |-0.5| = 0.5. Modul'''o''' is simply represented as ''mod'' in mathematics. Anyway, while we do not have TeX at the moment, you can try this instead - leave the original math formula as a <nowiki><!-- COMMENT --></nowiki>, and copy the image from Wikipedia (it will generate the image on preview, so you can download that and reupload it here. Don't overdo it of course.)

: ||x|| ( double | ) is what I was taught here at college, but I guess is not an standard, however I found what it seems is the standard, and used the UTF code to show it. However <*pre> is not happy with <*sub>, you should find a way around because mine doesn't look that good. By the way it was "greatest integer" not maximum, problems for using a direct translation. [[User:Qgpr|Qgpr]] 22:16, 5 Mar 2005 (GMT-5)

First shot at a TeX markup image. Using

<pre>
\begin{math}
b \star x \rightarrow \frac{b}{x} - (\frac{b}{x}\;mod\;1)
\end{math}

\addvspace{.2cm}

\begin{math}
e(n) = \left\{
\begin{array}{clrr}
n^3(\frac{100 - n}{50}); & 0 < n \leq 50 \\*
n^3(\frac{150 - n}{100}); & 51 \leq n \leq 68 \\*
n^3(1.274 - \frac{1}{50}(n\star3) - p(n\;mod\;3)); & 69 \leq n \leq 98 \\*
n^3(\frac{160 - n}{100}); & 99 \leq n \leq 100 \\*
\end{array}
\right\}
\end{math}

\addvspace{.2cm}

\begin{math}
p(x) = \left\{
\begin{array}{clrr}
0.000; & x = 0 \\*
0.008; & x = 1 \\*
0.014; & x = 2 \\*

I came up with

[[Image:Texerratic.png]]

Kind of cramped. Does it meet the approval of you two? Looking for revisions before I even post it. Especially since I forgot how to properly represent a custom operator (\star). Is that how? [[User:Sheep|Sheep]] 03:32, 6 Mar 2005 (UTC)

This seems better:
<pre>\begin{equation}
E(n) = \left\{ \begin{array}{ll}
\frac{n^{3} \left(100 - n\right)}{50}, & \textrm{if $0 < n \leq 50$} \\
\frac{n^{3} \left(150 - n\right)}{100}, & \textrm{if $51 < n \leq 68$} \\
n^{3} \left(1.274 - \frac{1}{50}\left\lfloor\frac{n}{3}\right\rfloor -p\left(n \bmod 3\right)\right), & \textrm{if $69 < n \leq 98$} \\ 
\frac{n^{3} \left(160 - n\right)}{100}, & \textrm{if $99 < n \leq 100$}
\end{array}\right.
\end{equation}

\begin{equation}
p(m) = \left\{ \begin{array}{ll}
0.000, & \textrm{if $m = 0$} \\
0.008, & \textrm{if $m = 1$} \\
0.014, & \textrm{if $m = 2$}
\end{array}\right.

But when I tested it on Wikipedia, there were a few problems, so if we do get around to installing Texvc, we'll have to go hammer those problems out. Also, I'd appreciate it if we could find the exact fractions for those decimalised numbers - after all, the computer works in binary, not decimal - hence we won't have 0.008, we might instead have 523/65536 (or maybe 8/1000, but the result would still be stored as a binary fraction) - [[User:Zhen Lin|刘 (劉) 振霖]] 07:22, 6 Mar 2005 (UTC)

I updated texerratic.png up there with something that looks more like yours. I didn't use Wikipedia for mine, I was using TeXnicCenter. I think the decimals are all right how they are, because they actually are more correct. I don't know exactly how the games handle decimal arithmetic, but it appears that the formulas use values accurate to 3 decimal places. (525/65536) or (523/65536) are not exactly 0.008, and if you put in those values, you'll get numbers that are off (I got about 6 points off for level 70). [[User:Sheep|Sheep]] 13:47, 6 Mar 2005 (UTC)

Mmm. Since the experience points have to be accurate to about 7sf - I think the fractions should therefore be accurate to 7sf as well. But it might well be that they did use integer multiplication + division (× 8  ÷ 1000) rather than a simpler constant floating point multiplication (× (1 + 402653/2<sup>24</sup>) × 2<sup>-7</sup>) - which is approximately how accurate a single-precision IEEE 754 binary fraction is. Funnily enough, IEEE 754 single-precision fractions are accurate to approx 7sf (without exponentiation) by defintion (this one is 0.008 correct to 11sf)). - [[User:Zhen Lin|刘 (劉) 振霖]] 14:40, 6 Mar 2005 (UTC)

Hmm. I just learned from Meowth that the game simply stores the values for these as constants in the game, so the fractions are just best-fit and the formula is not used in-game - [[User:Zhen Lin|刘 (劉) 振霖]] 14:44, 6 Mar 2005 (UTC)

So we need to reach a conclusion. There will be a note added that says these values are stored in the game as constants, not calculated. The formulas, I guess, do not have to be specific to any system of number storage now, so are we saying that the decimal constants are acceptable? [[User:Sheep|Sheep]] 15:04, 6 Mar 2005 (UTC)

===quick question===
Why does Level redirect here? An even better question is, why does this page link to Level, thus linking back to itself? --[[user:greengiant|greengiant]]

Sorry my reply is formatted wrong, I don't know how to do it normally yet.  Anyway, the last time I checked, [[Level]] is its own, seperate article.  Maybe they fixed the problem you saw before.  {{SUBST:Superbreeder]] [[User talk:Superbreeder|What's up?]] 23:30, 16 October 2008 (UTC)

== Modify this! ==

Can someone modify the erratic and the fluctuating part of experience? I want to understand it like all the other ones!

:I think those formulas should be explained.  It would help quite a lot of people who want to understand those formulas but haven't seen them before.[[User:Dullstar|Dullstar]] 02:16, 26 June 2010 (UTC)


== Color-Coded ==

I color-coded the exp type descriptions to more-or-less match the colors used on the graph. I did this to make it easier to distinguish them from eachother. I wonder where I can find the look-up table in the game, I bet I can simplify those two honking large piecewise formulas. [[User:Twigpi|Twigpi]] 15:51, 20 November 2007 (UTC)
:See [http://www.upokecenter.com/games/rs/guides/exptable.html http://www.upokecenter.com/games/rs/guides/exptable.html]. The "1,050,000" in one of the top columns is a typo (should be "1,059,860"). At Level 1, the Experience is always "0" (here, they have it at "1"). [[User:Ultraflame|Ultraflame]] 22:53, 10 December 2007 (UTC)

== Organize Pokémon ==

I really think there should be either a list of Pokémon by experience types or a category for each type.  You can find out on each particular Pokémon's page, but there is no way to find Pokémon based on their experience type. [[User:Cheesus Is Lord|Cheesus Is Lord]] 13:23 23 January 2008

I like this idea and think it would be useful. Anyone else agree? [[User:Eric the espeon|Eric the espeon]] 19:43, 25 November 2008 (UTC)
:Yes, but I don't know if it belongs on this page.  We could create categories, but I think I like the idea of another page better, like List of Pokémon by experience requirement, or something.&nbsp;&mdash;&nbsp;[[User:Laoris|Laoris]]&nbsp;<sub>([[User_Talk:Laoris|Blah]])</sub> 19:52, 25 November 2008 (UTC)
Makes sense, and link to that list from here? [[User:Eric the espeon|Eric the espeon]] 18:19, 4 December 2008 (UTC)

== ??? ==

If the formula returns a decimal, is the result rounded up or down? --[[User talk:Shiny Noctowl|<font color="black"><small>S</small><sup>h</sup><small>i</small><sub>n</sub><small>y</small> <sup>N</sup><small>o</small><sub>c</sub><small>t</small><sup>o</sup><small>w</small><sub>l</sub></font>]] 15:39, 26 May 2008 (UTC)
:Always rounded down, I believe. [[User:Ultraflame|Ultraflame]] 22:59, 26 May 2008 (UTC)

== Hmm... ==

Does anyone else think that a chart that lists the experience needed to reach each level in an experience group would be a good addition to this page? '''[[User:TTEchidna|<span style="color:#FF0000">''TTE''</span>]][[User talk:TTEchidna|chidna]]''' 05:20, 1 July 2008 (UTC)

::I added the charts, but, as I had a computer program generate them, I haven't been able to check the piecewise ones yet. It would be good if someone else could check the piecewise functions ("erratic" and "fluctuating") to make sure they're correct. --[[User:Shiny Noctowl|<font color="black"><small>S</small><sup>h</sup><small>i</small><sub>n</sub><small>y</small> <sup>N</sup><small>o</small><sub>c</sub><small>t</small><sup>o</sup><small>w</small><sub>l</sub></font>]] 00:15, 29 September 2008 (UTC)

== Pokémon Gold/Silver Version ROM - Hack-O-Matic - "Secret" Experience functions ==

I'm sure someone else has noticed that if you use the ROM hack tool Hack-O-Matic to open a Pokémon Gold/Silver ROM and edit Pokémon, there will be eight "experience gradient" choices for each Pokémon as opposed to the four that were actually used in Generation II. I've figured out three of the four "secret" functions, and due to a glitch in Hack-O-Matic I can't examine the fourth one.<br>
Hack-O-Matic displays the eight experience functions as eight "types" (the numbers go from Level 2 to 100):

Unknown due to glitch in Hack-O-Matic. Hack-O-Matic provides graphs for each experience function, but they may not be accurate. Do you want me to upload that graph's picture anyway?<br>
Are these "hidden" experience functions notable enough to be added to the article somewhere? Thanks. [[User:Ultraflame|Ultraflame]] 20:44, 12 October 2008 (UTC)

I dont understand any of this? Could you make it clearer for the average user to be able to read, if an average person sees that they wont be able to understand it, only smart people will --[[User:Guardian|<font color="#0000FF">Guardian</font>]][[Special:Contributions/Guardian|<font color="#FFFF00"> of</font>]][[User talk:Guardian|<font color="#FF0000"> Earth</font>]] |[[GSDS|<font color="#00FF00">SGMS 2010</font>]]
:When a Pokémon gains experience it levels up.  Different Pokémon level up at different rates, and take different amounts of experience to gain each level.  Some Pokémon level up faster than others.  The amount of experience a Pokémon needs to gain a level is determined by one of eight possible formulas.  That's really the premise of the whole article.&nbsp;&mdash;&nbsp;[[User:Laoris|Laoris]]&nbsp;<sub>([[User_Talk:Laoris|Blah]])</sub> 18:27, 4 December 2008 (UTC)

oh ok thank you, it was that last line "The amount of experience a Pokémon needs to gain a level is determined by one of eight possible formulas." I didnt really get till you explained it. I just thought they made the pokemon that way, i wasnt aware there was a formula, if this is in the article, can we have the easier to understand version, your version, underneath the complicated bit. --[[User:Guardian|<font color="#0000FF">Guardian</font>]][[Special:Contributions/Guardian|<font color="#FFFF00"> of</font>]][[User talk:Guardian|<font color="#FF0000"> Earth</font>]] |[[GSDS|<font color="#00FF00">SGMS 2010</font>]]

-->{{unsigned|Eric the espeon}}<small>''; massive amount of data hidden by {{u|the dark lord trombonator|trom}}.''</small>

:Already in [[List of Pokémon by effort value yield]]. [[User:Ultraflame|Ultraflame]] 00:42, 21 November 2009 (UTC)
No, that is EV yield.. The list I provided was base EXP yield. Quite a major difference there. [[User:Eric the espeon|Eric the espeon]] 17:57, 21 November 2009 (UTC)
:If you take a look at the article, there's a column marked "Exp.", which contains exactly the same data that you have provided. Confusing, I know. [[User:Ultraflame|Ultraflame]] 19:06, 21 November 2009 (UTC)
Ok, fair enough. This article should probably link to that list then, no? [[User:Eric the espeon|Eric the espeon]] 21:59, 21 November 2009 (UTC)

==Negative EXP==
According to the "medium slow" formula, the EXP for level 1 should be -54. This is exploited in the [http://tasvideos.org/950M.html Pokémon Blue TAS]. However there's no sign of this in the article. Was it fixed in later games? {{unsigned|Gyorokpeter }}
:It was fixed as of Generation III at the latest, I believe. According to the article, "Due most likely to the issue of speed when using these formulas, the GBA games will simply use a {{wp|lookup table}} for each value of any type instead of computing them. Because of this, these formulas are not actually part of the game mechanics." [[User:Ultraflame|Ultraflame]] 05:41, 22 December 2009 (UTC)

== Experience gain in battle ==
The section on the experience gained in battle only mentions the total experience gained, and not how experience is spread throughout multiple participants in the battle. That information seems like a useful mechanic and should be appended by someone who can add it. --[[User:Naokohiro|Naokohiro]] 19:21, 9 January 2010 (UTC)
:It is divided evenly among participants, unless some participants have EXP share or whatever. In this case, they receive their share plus the bonus from the held item. &mdash;'''<span style="font-family:Verdana"><span style="color:#000">darklord</span>[[User talk:The dark lord trombonator|<span style="color:#0047AB">trom</span>]]</span>''' 03:56, 10 January 2010 (UTC)
::How is it divided among arbitrary amounts of Pokémon involved in the battle, and Pokémon with Exp. Share, including cases where Pokémon have both an Exp. Share and participated in the battle? There are many different cases. For example, when some Pokémon have Exp. Share and some don't, but some of the Pokémon with Exp. Share participated and some didn't, but also some Pokémon without Exp. Share that did participate, etc. --[[User:Naokohiro|Naokohiro]] 04:41, 14 January 2010 (UTC)
:::I don't know exactly how experience is divided among multiple Exp. Share holders (does each Pokémon with Exp. Share receive (1/(number of Exp. Shares + 1))*(total experience), or does each receive (1/2)*(total experience)*(1/number of Exp. Shares), or something else?), but the experience '''that is not allocated solely as a result of Exp. Share being held''' is always divided evenly among the participants of the battle, regardless of whether or not those participants hold Exp. Share. [[User:Ultraflame|Ultraflame]] 06:22, 14 January 2010 (UTC)

== Switching??? ==

I'll give an example.

Say I have a Charizard out, and the opponent has Venusaur. The opponent switches to Blastoise, and later I switch to Raichu. If the opponent switches back to Venusaur, and I KO it, will my Charizard still gain exp?

== Errors with formulas? ==
I was just double-checking the erratic output based on the formula given, when I realized that the given formula is impossible, in programming terms. Specifically, the game would never output two values for levels 50, 68, and 98, as the current formula shows it does. So I checked to see what the correct distribution of the formulas was, and came up with the following: level 50 could go either way, as both formulas it is attributed to result in the same output, level 68 is calculated based on the second formula given, and level 98 is calculated on the final formula. In other words, the actual division of the formulas should be something along the lines of the first applying to levels below or equal to 50, the second applying to levels greater than 50 but less than or equal to 68, the third applying to levels greater than 68 but less than to 98 (or, to keep similar formatting, apply to levels greater than 68 but less than or equal to 97), and the final one applying to levels greater than or equal to 98 (or, to keep formatting, apply to levels greater than 97). [[User:Glitchfinder|Glitchfinder]] 03:31, 6 May 2010 (UTC)

It would also appear that quite a bit has been left out of the fluctuating piecewise function. Specifically, it would appear that the formula used for levels one through 14 will change based on the level modulo 3, resulting in three different yet very similar formulas for these levels. The middle levels, from 15 to 34, remain with the same formula that is given. However, it would appear that there are two separate formulas used for levels 35 to 100, determined by the level modulo 2. Here is the code I was using to test the function, which is written in Ruby:

 test.fluctuating[1] = 0
 for i in 2...101
   if i >= 1 && i < 15 && i % 3 == 0
     val = ((i.to_f ** 3.0) * ((24.0 + ((i.to_f) / 3.0)) / 50.0))
   elsif i >= 1 && i < 15 && i % 3 == 1
     val = ((i.to_f ** 3.0) * ((24.0 + ((i.to_f - 1.0) / 3.0)) / 50.0))
   elsif i >= 1 && i < 15 && i % 3 == 2
     val = ((i.to_f ** 3.0) * ((24.0 + ((i.to_f + 1.0) / 3.0)) / 50.0))
   elsif i >= 15 && i < 35
     val = ((i.to_f ** 3.0) * ((14.0 + i.to_f) / 50.0))
   elsif i >= 35 && i <= 100 && i % 2 == 0
     val = ((i.to_f ** 3.0) * ((32.0 + (i.to_f / 2.0)) / 50.0))
   elsif i >= 35 && i <= 100 && i % 2 == 1
     val = ((i.to_f ** 3.0) * ((32.0 + ((i.to_f - 1.0) / 2.0)) / 50.0))
   end
   test.fluctuating[i] = val.truncate
 end
Please note that the code is given as a demonstration of how the formulas are chosen, and does not include the necessary setup for the test variable. I don't know the Wikipedia math functions well enough to replace the image, so it would be a good idea for someone else to do it instead. [[User:Glitchfinder|Glitchfinder]] 05:17, 6 May 2010 (UTC)
:I believe that the modulo operator business is already covered in the formulas, using the floor function symbol (looks a little like square brackets). But I do agree that the erratic functions' domains should be clarified as you said. [[User:Ultraflame|Ultraflame]] 05:25, 6 May 2010 (UTC)
::That would certainly explain the problem. There should probably be a note stating that those values are actually encased in a floor function, and not simply placed within brackets. (I had to look quite closely to see that they were in fact the floor function symbols, and not simply brackets, like I had assumed they were) [[User:Glitchfinder|Glitchfinder]] 05:47, 6 May 2010 (UTC)

== Understanding the formulas ==

Could anyone tell me what is ment with "N" in the formulas?
I can't find it anywhere on the page. {{unsigned|Ragnearoa}}
:"n" generally means "number" when used in equations as a variable, in this case... I believe the "n" stands for the base experience given out by a Pokemon. ▫▫'''[[User:Tina|<span style="color:#e072a9;">ティナ</span>]]'''<sup>[[User talk:Tina|<span style="color:#728084;">♫</span>]][[Special:Contributions/Tina|<span style="color:#728084;">★</span>]]</sup> 15:21, 20 May 2010 (UTC)
::"n" actually represents the level of the Pokémon. "e(n)" is therefore the number of Exp. Points a Pokémon needs to get from level 1 to level "n". [[User:Ultraflame|Ultraflame]] 01:21, 21 May 2010 (UTC)

== Erratic formula ==

The erratic formula's piecewise functions are defined inclusively in all inequalities, and thus overlap.
[[Image:Math-formula5.png|left]] [[Image:Expcalc_erratic.png|right]]
<div style="clear:both"></div>
The left formula is how I believe it should be, the right is the current one. -- [[User:Pokey|Pokey]] 07:38, 27 May 2010 (UTC)
: At the overlaps, the values are equal. [[User:Ztobor|Ztobor]] 22:34, 15 July 2010 (UTC)

== Does Not Compute ==
The Trivia sections on the species pages for Arceus, Blissey and Chansey all state that they give 13,933 experience at level 100 when owned by a Trainer. But based on the way that the experience given in battle formula is written right now (with ''a'' being 1 plus an additional possible 1.2 depending on Trainer status, trade, and foreign language), it only equals 8,014, not 13,933.

''a''=2.2   ''b''=255   ''L''=100   ''a''+''b''+''L''=56,100   56,100/7=8,014

Add a Lucky Egg (multiply by 1.5) onto that and you only get 12,021. The only way to get the 13,933 is to multiply 1.5 for the trade and 1.7 for the foreign language ''after'' the initial Trainer experience (with ''a'' being 1.5) has been calculated, not to add .5 and .2 to ''a''. --[[User:Phantomjunkie|<span style="color:red">Phantom</span>]][[User talk:Phantomjunkie|<span style="color:black">Junkie</span>]] 17:17, 17 July 2010 (UTC)
:We'd better look into that. Perhaps you don't add 0.5 to a, but multiply a by 1.5 instead. I'll see about it. [[User:Ztobor|Ztobor]] 02:50, 22 July 2010 (UTC)
::Hold on, you mean: if you calculate 1.5x for the Lucky Egg, 1.7x for the foreign language trade, and 1.5x for the Trainer battle as well. 
:::If we're going by that logic, it might actually be that you multiply everything, instead of adding to the multiplier. In which case it would actually be 14,753 experience points. I'll still have to look into it. [[User:Ztobor|Ztobor]] 02:58, 22 July 2010 (UTC)
::::Okay, I found out. I tried battling against a trainer's Level 28 Mime Jr. with a German-traded Gabite holding a Lucky Egg. The base Exp. is exactly 312, and it gained 1193, which is 1.5 x 1.7 x 1.5. So yes, you actually do need to multiply 1.5 twice, and the article as it stands now is wrong. [[User:Ztobor|Ztobor]] 03:18, 22 July 2010 (UTC)
:::::Fixed. [[User:Ztobor|Ztobor]] 03:57, 22 July 2010 (UTC)

== Minor wording issue ==
I didn't want to just go in and edit this without asking. The section on the Experience Underflow glitch contains the following sentence:
''It is due to this bug that no level 1 Pokémon can be found in the wild without glitching or hacking the game, and why, even though level 2-4 Pokémon can be found wild, Pokémon hatched at level 5 in the first two generations.''
However, since breeding and, by extension, hatching eggs wasn't added until Generation II, shouldn't the sentence be changed to state that "Pokémon hatched at level 5 in the second generation"? The following paragraph refers to level 5 hatching in Generation III, so I don't feel it's necessary to add it here. --[[User:Phantomjunkie|<span style="color:red">Phantom</span>]][[User talk:Phantomjunkie|<span style="color:black">Junkie</span>]] 08:08, 19 July 2010 (UTC)
:Changed to "''Pokémon hatched at level 5 when eggs were introduced in Generation II.''" [[User:Ultraflame|Ultraflame]] 01:30, 20 July 2010 (UTC)

== Use of asymptotic notation ==

It's not really appropriate to use asymptotic notation in the manner this article does currently: the notion is not really useful unless the functions tend to 0 or infinity, as we can write many statements that say equally true and unhelpful things. For example, all six functions in the article are O(1) at n=100, or O(n), or O(n^10) (using the lim sup definition in the Wikipedia article, for example), none of which show the detail we want.

In other words, the notation is effectively meaningless the way it is being used. Perhaps considering f(x)-f(100) would be better.

Small extra note: to be rather fussy, similar remarks could be made about the way the article used "continuous" before I removed it: these functions are defined on the integers, and since there is no way of talking about limits on a finite set of integers, you can't talk about continuity either. (The integers are called discrete or totally disconnected because of the way the topologies on them must be defined, if anyone wants more detail.) Of course, this also means you can't use asymptotic notation in this case at all... [[User:Chappers|Chappers]] 00:32, 24 July 2010 (UTC)

: Alright, I'll remove that part. A friend of mine also said it was inappropriate too.
:: Also, about the "continuous" function part, I can see why it's notation abuse now. I just meant to say that it wasn't piecewise, and could be represented as one function. I guess "polynomial" is a good compromise if we can't really find a suitable word for it. [[User:Ztobor|Ztobor]] 19:42, 24 July 2010 (UTC)

== Where to put this? ==

[[File:ExpToNextLevel.png|300px|thumb|right|A graph showing the number of experience points required to go from one level to the next.]]

I created a table with the number of experience points required to go from one level to the ''next'' level, not just from level 1 to a level, but the formula won't fit anywhere.

Image is to the right. [[User:Ztobor|Ztobor]] 20:26, 24 July 2010 (UTC)

== Misleading names ==

The Medium Slow (a.k.a. Parabolic) function is not actually strictly slower than the Medium Fast (a.k.a Cubic) function.

The only functions that are actually strictly ordered in terms of speed of levelling up are the Slow, Medium Fast, and Fast functions. The other three are all quirky.

What I'd suggest is renaming the Medium Fast function to simply Medium, and rename the Medium Slow function to... something. I still need to come up with a name, hence why I haven't actually edited the page yet. [[User:Ztobor|Ztobor]] 00:44, 1 August 2010 (UTC)

:You could just change it to "Parabolic", but do leave a reminder that there exist different names for the experience functions. In my opinion "Erratic" and "Fluctuating" are okay names for their respective functions. [[User:Ultraflame|Ultraflame]] 04:51, 1 August 2010 (UTC)
::Or, to go with the quirky nature of the function compared to the others, rename it to "Quirky". Because "parabolic" is a huge misnomer. What do you think? (I didn't say anything about Erratic or Fluctiating... o_O) [[User:Ztobor|Ztobor]] 17:25, 1 August 2010 (UTC)
:::Hard to say, since you're the first person I've ever seen to refer to that experience function as "Quirky". I just mentioned Erratic and Fluctuating because you didn't, and I wasn't sure what your own opinion was on those names. [[User:Ultraflame|Ultraflame]] 22:07, 1 August 2010 (UTC)
::::Well, I didn't mention those, but I think they're perfectly fine. It was just the four that were "ranked" by speed that I had a problem with - and even then it's only the Medium Slow one simply because it doesn't even fit into that rank nicely. [[User:Ztobor|Ztobor]] 13:34, 2 August 2010 (UTC)
::::Actually, even those three names should probably be changed to "Cubic", "Fast Cubic", and "Slow Cubic". It just doesn't make sense to rank them all by speed if they vary so much. [[User:Ztobor|Ztobor]] 13:36, 2 August 2010 (UTC)
:::::You could try something like "Fast (Cubic)", "Medium (Cubic)", and "Slow (Cubic)". As for 1059860, we might be able to get away with calling it "Parabolic" and adding a note that the name only refers to the existence of a "not-purely-cubic" part in the function.

== New Exp. gain formula ==

I'm doing research on it right now, by watching playthroughs. Apparently, there's actually a ''+1'' in the formula >_> [[User:Ztobor|Ztobor]] 02:47, 25 October 2010 (UTC)

Okay, here it is:

[[File:Delta_exp_gen5.png]]

The only differences in the formula is that the 7 has now been changed to a 5, and the d<sub>L</sub> represents the level relationship factor, which I'm still trying to figure out. Also, a constant of 1 is now added to all experience point yields, probably to prevent defeated monsters from yielding 0 experience points due to a low d<sub>L</sub> modifier.

::There is, but I don't know where it applies. [[User:Ztobor|Ztobor]] 14:00, 7 November 2010 (UTC)
:This formula can't be correct; no matter where I apply or don't apply rounding, I get slightly higher or slightly lower values than the experience I actually get in the game. Also, unless this one formula gets special treatment out of all the formulas in the game, the Pokémon games round down after every division or any other operation resulting in a non-integer, so if this were literally it, the level factor could never be anything between 0 and 1.

:::Could you include some of your calculations and data? It could speed up finding out what's going on here. [[User:Dragonfree|Dragonfree]] 23:00, 13 November 2010 (UTC)
::::Okay, take your first battle with the other starters - Level 5 vs. Level 5 (a level multiplier of 1) gives you 43 experience points. The starters' base yield is 28, which is multiplied by 1.5 because it's a trainer battle, giving you 42. No other multipliers apply, so you add 1 to 42 which gives you 43.

== Base EXP ==

The page currently says that the Pokemon that gives the most base EXP is Blissey with 608 - only every other page on this wiki and on other sites says that it's only 255. (Tabunne, for the record, has a yield of 390.) It also says that the fifth-gen starters give the least at 28; this time, the NUMBER is right, but Magikarp still apparently only gives 20. What gives? --[[User:HeroicJay|HeroicJay]] 22:51, 25 October 2010 (UTC)

== Report anomalies in the new Exp. gain formula ==

As far as we know right now, this is the new formula for experience used in Gen.5:

If you think this formula might not apply to a certain type of battle, append your case to the bottom of this post with the following data:

*The Pokémon that were involved in the battle, and their levels.
*Whether the battle was a Trainer battle or not.
*Whether the Pokémon involved were holding any items.

On the GameFAQ's forums, a user named JakeisaLie reported the following: A Level 48 Tabunne, was defeated by a level 52 Rotom holding a Lucky Egg, and yielded 5119 experience points instead of 5201 as the formula predicts.

The level difference multiplier, in this case, seems to be 72/79 (48 / 52+(2/3)), instead of 50/54 (48+2 / 50+2). [[User:Ztobor|Ztobor]] 16:25, 23 December 2010 (UTC)

=== Watched some playthroughs of the first bit of the game... ===
... and what I found is below. I didn't record what Pokémon were used to battle, because I didn't think it was relevant. None of the Pokémon were holding any experience-affecting items. Format is <pre><level of player's Pokémon> vs. <level of defeated Pokémon> <defeated Pokémon>: <Exp. gained> (formula predicts <exp. expected from formula>)</pre>

: Thanks for the info, but just to clarify - are these Trainer battles? Because the formula seems to identify them as such. [[User:Ztobor|Ztobor]] 22:45, 26 December 2010 (UTC)

I have to say, despite the formula not being completely accurate, it does give a pretty good rough idea of how much experience you're going to get. [[User:Ultraflame|Ultraflame]] 22:33, 1 January 2011 (UTC)

: I guess so. It's just that I just know that people are going to be disappointed when they don't actually get 1,581,409 points for defeating a level 100 Blissey in the way I mentioned. [[User:Ztobor|Ztobor]] 21:05, 2 January 2011 (UTC)
:: Although, given the looks of the variations in this formula, it looks like that fight would yield ''more'' than 1,581,409. [[User:Ztobor|Ztobor]] 21:09, 2 January 2011 (UTC)

Existing formula tends to overestimate if the attacking Pokémon is higher level, and underestimate if the defending Pokémon is higher level (what you hinted at with the Blissey example). (Existing formula is correct if the two Pokémon are the same level.) [[User:Ultraflame|Ultraflame]] 05:45, 3 January 2011 (UTC)
: I'm pretty sure now that it involves square roots (or other such concave functions) in some way. That means that my formula only underestimates for a little of the time - and then it goes back to overestimating. [[User:Ztobor|Ztobor]] 03:01, 8 January 2011 (UTC)

== ERRATIC behaviour in Mathematica ==

So, I went to type in the EXP per level into Wolfram Mathematica 6, in an attempt to come up with both better graphs and interesting phenomonons. The non-piecewise functions turned out fine. However, the erratic and fluct. formulas kept coming up with strange behaviour in their plots, which I was able to filter out. However, look at this plot for the erratic formula:

[[File:Mathematica_Erratic_Plot_Derivitive.png]]

This is the derivitive of the function of the Erratic experience group. Look at the range 68-98. Any ideas as to what is causing this? I had typed the formula in direstly as was shown on the article. [[User:TruePikachu|--TruePikachu]] 20:37, 20 November 2010 (UTC)

:<nowiki>*Facepalm*</nowiki> Just zoomed in, seems to be caused by the Floor() function and the erratic nature of that portion of the growth curve, which is why it didn't show up for Fluct. The formulas weren't designed for this kind of manipulation...time to weite an interger-based derivitave function to better model this...

:Anyway, any ideas as to wether or not I should undergo this project? I can easily cut out the inputted formula (It is harder to include it rather than exclude it). The GenI formulas are rather well established, being elementry curves, but the GenIII curves I can do lots of research into, and add to the article under a different heading. For example, I can easily generate a graph of the 'changing multiplier' for these two functions, or superimpose all parts of the piecewise function (so someone could see what happens if one part of it is used for the entire function). [[User:TruePikachu|--TruePikachu]] 20:47, 20 November 2010 (UTC)
::I already created a changing multiplier graph. Third one down from the top. I also created an "EXP per level" graph (shown here on the talk page), but for lack of a place to put it, haven't put it onto the main page yet. [[User:Ztobor|Ztobor]] 03:19, 22 November 2010 (UTC)

== Reshiram and Zekrom don't gain experience? ==

For some reason, people are editing this onto the article, even though it isn't true, at least from what I've seen of the playthroughs. Why do people think that it doesn't yield experience? [[User:Ztobor|Ztobor]] 00:59, 30 November 2010 (UTC)

::When facing the wild version mascot before facing N, defeating it yields no Exp, as when the battlt ends, it'll just be there in the overworld as if nothing happened. Facing the one N has will yield Exp though. [[User:Shiramu Kuromu|Shiramu Kuromu]] 03:18, 12 December 2010 (UTC)

== Question ==

If there was a Pokémon that would change it's Exp group upon evolution, what would happen? [[User:Shiramu Kuromu|Shiramu Kuromu]] 03:18, 12 December 2010 (UTC)
:In Generation III at least, the Pokémon would change level so that it would be consistent with the what the new group's experience formula would dictate.
:For example, if you hacked a Pikachu (1000000 at level 100) so that it would evolve into Gyarados (1250000 at level 100) at level 20, the Pikachu would only need 8000 exp. points to reach level 20. So suppose that the Pikachu receives 8000 exp. points, reaches level 20, and is allowed to evolve. But since Gyarados is in a different experience group, the Pokémon would actually drop down to level 18 (for Gyarados's group, 8000 points is only sufficient for level 18) immediately after evolution is complete. Meaning that when you check your Pokémon menu right after evolution, the Pokémon will appear as level 18, with 8000 exp. points.
:This has apparently been observed with a Generation III ROM, but I don't know exactly what would in other Generations. [[User:Ultraflame|Ultraflame]] 04:55, 12 December 2010 (UTC)
:Just realized that a potential question might arise with my example: Would the newly-evolved Gyarados attempt to learn {{m|Bite}} (a level 20 move), even though it's technically level 18 after evolution? Unfortunately I don't have the answer to that particular question. [[User:Ultraflame|Ultraflame]] 05:06, 12 December 2010 (UTC)
::Based on what you've said about the situation, I'd guess no - after evolution, the new level is 18, period. Otherwise, the bug would be that it stays at Level 20, but as soon as it gains experience points, it reverts to 18. [[User:Ztobor|Ztobor]] 15:46, 23 December 2010 (UTC)
:::Well, a regular Magikarp evolving into Gyarados at level 20 would immediately try to learn Bite upon evolution (without leaving the evolution screen). In other words, we haven't even seen the new level of the Gyarados until after it attempts to learn Bite. Basically it's a question of when does the game "notice" that the Pokémon's experience group has changed - immediately upon evolution (i.e. while the evolution screen is active) or immediately after leaving the evolution screen? [[User:Ultraflame|Ultraflame]] 17:09, 23 December 2010 (UTC)
::::That's a good point, actually. We'd need somebody to test that out. [[User:Ztobor|Ztobor]] 01:52, 24 December 2010 (UTC)

== Level multipliers in the new Exp. gain formula ==

We're going to have to change that article - it certainly is not adding the levels by 2 and dividing them.

I'm getting a table set up with the approximate multipliers. Perhaps we can figure something out. [[User:Ztobor|Ztobor]] 05:19, 27 December 2010 (UTC)
