I posted about building a big decision tree that proved that player 2 could force a win by player 1 in tic tac toe. Turns out I was reading my results incorrectly (a result of ”2″ at a node meant player 2 could not force a player 1 win). That sucks.

I have proven the inverse of my hypothesis, so that’s something! Next up to see if P2 can never win (so P1 wins or draws).
