Hand-built heuristics and shallow search
Open loop
Decide a whole short sequence of columns in advance, judge it against many imagined disc streams at once, and play only its first move before planning again.
Approaches
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.
Hand-built heuristics and shallow search
Scores visible board traits, adds them together, and plays the highest-valued column.
Oracle and curriculum research
Let a planner cheat (show it the hidden numbers and the discs still to come) then try to teach a player who cannot cheat.
No approach page matches that search.
