Hi guys!

I'm a spanish student, and i'm doing an investigation work for the university about the play of poker. Specifically of Texas Hold'em Poker. The paper that we're basing on is "Estimating the strength of poker hands by integer linear programming techniques" i need to know if it's legal to use that kind of computations to win. If there's someone who uses it and if it's something easy to do. I also want to know if someone knows how "World series of poker" computes the percentages of the possibility to win.enter image description here

Thanks in advance :)
