Fair expectimax reference (D3/D4)
The reference search looks four moves ahead, averages the sampled chance outcomes, and uses a hand-tuned board evaluator at the bottom.

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.
Fair expectimax
Look a few moves ahead, take the best column on your own turns, and average over every sampled disc the game might deal.
Hand-built heuristics and shallow search
Scores visible board traits, adds them together, and plays the highest-valued column.
Lifetime objective
Judge a move by how much longer the game will still last, rather than by how many points it scores right now.
No approach page matches that search.
