Of course he also explains some of the math. Thanks for contributing an answer to MathOverflow! There's actually another limitation in that it's impossible for one letter X or O to have won in two different ways without a common cell (again, they would have won in a previous move), meaning that: so I thought the invalid states are the states where we have two winning lines in the same direction(vertically or horizontally), this is wrong solution, there are states where there are two winning lines not in the same direction Check whether the current player won the game or not. But we can actually ignore that since there's no way to win two ways without a common cell without having already violated the "maximum difference of one" rule, since you need six cells for that, with the opponent only having three. That might work, since the AI takes an input of the partial probabilities for each layout. [4], The book is long (732 pages),[4] organized into 49 chapters and four sections.
