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.

4 approaches of 87

Constructive planning

Plan a whole rise cycle toward a target board shape, so that later rises set off stacks prepared in advance.

Constructive planningfeatured

Viability controller

Classifies each move as charge, dig, release, repair, or emergency, then picks the best move of that kind. It scored well below the one-move-ahead reference.

Constructive planning

Cycle abstraction

Choose one of five plans for the whole five-drop cycle, then let a model decide which plan fits the board.

Stacking a column for a later chain

Reward the search for building columns that are one quiet drop away from collapsing in several waves, and see whether deliberately stored energy makes games longer.
