Erratic (600000) E = -1/50*l^4 + 2*l^3 for level<=50

http://www.math.miami.edu/~jam/azure/forum/tuff/ultimatebb.php?ubb=get_topic;f=1;t=001260

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

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

Simplify the formulas

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.

2*(1 - 0.01n)*(n3)
= int( 2n3 - 0.02n4 )

(  1 - ((n - 50)*0.01)  ) * (n^3)
= int( 1.5n3 - 0.01n4 )

(1.6 - 0.01n) * (n3)
= int( 1.6n3 - 0.01n4 )

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()." 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. Qgpr 20:03, 5 Mar 2005 (GMT-5)

|x| is modulus - gives the absolute value of function, i.e. |-0.5| = 0.5. Modulo 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 <!-- COMMENT -->, 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. Qgpr 22:16, 5 Mar 2005 (GMT-5)

First shot at a TeX markup image. Using

\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 \\*
\end{array}
\right\}
\end{math}

I came up with

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? Sheep 03:32, 6 Mar 2005 (UTC)

This seems better:

\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.
\end{equation}

File:Erratic experience levels equation 1.png
File:Erratic experience levels equation 2.png 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) - 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). 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 + 402653/2²⁴) × 2^-7) - 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)). - 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 - 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? 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? --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]] 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!

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. Twigpi 15:51, 20 November 2007 (UTC)

See 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"). 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. Cheesus Is Lord 13:23 23 January 2008

I like this idea and think it would be useful. Anyone else agree? 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. — Laoris _(Blah) 19:52, 25 November 2008 (UTC)

Makes sense, and link to that list from here? Eric the espeon 18:19, 4 December 2008 (UTC)

???

If the formula returns a decimal, is the result rounded up or down? --S^hi_ny ^No_ct^ow_l 15:39, 26 May 2008 (UTC)

Always rounded down, I believe. 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? TTEchidna 05:20, 1 July 2008 (UTC)

yes MathijsP 07:22, 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. --S^hi_ny ^No_ct^ow_l 00:15, 29 September 2008 (UTC)

the "Erratic" one is messed up. lvl 98 is 1.2 million, and lvl 99 is under 600,000. also, thats a lot of text, so, i added the show/hide ability. -- MAGNEDETH 00:24, 29 September 2008 (UTC)

It's still messed up. Can you fix it please? --S^hi_ny ^No_ct^ow_l 00:27, 29 September 2008 (UTC)

i dont know how to fix it, i just added the show/hide things. im just noting its not right. you said you had a computer do it. try again? -- MAGNEDETH 00:29, 29 September 2008 (UTC)

The formula for Level 98 comes out to 583539, which is correct. Ultraflame 23:05, 29 September 2008 (UTC)

well thats fine, but currently it says lvl 98 is 1185901, which it wrong. -- MAGNEDETH 23:21, 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.
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?
Are these "hidden" experience functions notable enough to be added to the article somewhere? Thanks. 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 --Guardian of Earth |SGMS 2010

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. — Laoris _(Blah) 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.
