Hello Luigi,
I just found that I could get the handranks.dat file from the stand-alone version in PokerPredictor_v1.0.zip

Regards,
Guille

Hello Luigi,
the link to the handranks file is broken, and I cannot run the program without it (I get an error when executing the function in BuildTable.mexw32). Could you please re-post it?

Regards,
Guille

I keep getting invalid mex file or Mex file entry point is missing… Any suggestions? Please, make this work on mac and linux. I don’t know enough of C to translate to matlab etc, but maybe someone could do that and see if performance is still good?

same here… Any solution? I’ll look for one otherwise, but would be nice not to have to…

Cheers and big up for what looks like a pretty awesome tool.

I am sorry but I don’t have a linux system so I can not look for the error.

Just one thing, if I am not wrong gcc should be a C compiler not a c++ one.

I hope someone is able to compile linux files and send them to me. I will share those files avoiding this complicate compiling operation.

Hi,

I have an error while compiling the cpp files:
There’s probably something wrong on memset in line 50.
Unfortunately the error message is in german:

BuildTable.cpp: In function »void mexFunction(int, mxArray**, int)«:
BuildTable.cpp:50: Fehler: »memset« wurde in diesem Gültigkeitsbereich nicht definiert

I have run Matlab 7.7. on Ubuntu 9.04 gcc 4.3.3.

Best regards,
Horst

you did not make a mistake regarding odds. please do not change your calculations (although the spelling is “odds”, not “odd”)! the italian “quota” is the same definition as “gambling odds” in english.

for example, a payout of $2 for every $1 bet is an odds of 2:1. This is what’s used in poker as well. you are also right that there is another definition called the probability definition of odds. (1-p) / p is the “odds against”. and the inverse, p / (1-p) is the “odds in favour”. BUT the probability definition is NOT used in gambling and poker. =)

f = edge/odds
= EV / payout
= (p*payout-[(1-p)*losses])/payout
= (p*odds/(1-p*odds))/odds
= (p*(1+odds)-1)/odds
• f is fraction of bankroll to bet
• p is probability of winning
o in poker this is changed to probability of winning + tying
o
• odds here refers to gambling definition of odds
o i.e. a 2:1 odds refers to $2 payout for $1 bet on a win
• EV is the expected value.

Example
Assume p=50%, odds=2.
Then according to the Kelly criterion the player should bet 25% of his or her bankroll, where bankroll is the player’s current wealth and does not include any money in the pot (future wealth).
