I'll take a small issue with the end of the article that claims linear programming is used for game theory work in poker. With the exception of Andrew Gilpin's work using the "Excessive Gap Technique"[1], almost no poker game theory work relies on linear programming. Instead, the majority of work is on iterative game tree solutions like "Counterfactual Regret Minimization" [2].
In general, real-world games with imperfect information and stochastic outcomes (like poker) are just too large to represent in normal form.
