Shannon: search and evaluation for computer chess

Shannon described how a computer could generate chess moves, search continuations and evaluate positions. He contrasted fixed-depth exploration of all variations with selective search guided by promising moves and unstable tactical positions.

What is recorded here?

Shannon described how a computer could generate chess moves, search continuations and evaluate positions. He contrasted fixed-depth exploration of all variations with selective search guided by promising moves and unstable tactical positions. Chess made limited computation a concrete design problem. An exhaustive tree grows rapidly, so Shannon examined evaluation functions, move-generation subprograms and selective continuations. This is a human-designed AI method whose approximations differ from an exact game specification.

Scientific scope

The paper is a programming and search proposal. It does not report a strong implemented player, solve chess or guarantee that heuristic evaluation and selective search select the best move.
