Memory depth of finite state machine strategies for the iterated prisoner's dilemma
T. J. Gaffney, Marc Harper, Vincent A. Knight
We develop an efficient algorithm to determine the memory-depth of finite state machines and apply the algorithm to a collection of iterated prisoner's dilemma strategies. The calc…
