Each page here is one theory of how to choose a column, grouped by the technique it uses; the engines that play the games and the instruments that measure them live under Engines and Diagnostics.
Judge a move by how much longer the game will still last, rather than by how many points it scores right now.
Let a planner cheat (show it the hidden numbers and the discs still to come) then try to teach a player who cannot cheat.
Instead of searching ahead, train a model on past games to judge a board or pick a column, and learn why that kept failing.
No approach page matches that search.
