Nicolas Findler worked on and off for 20 years on a cognition-based poker-playing program for Five-Card Draw   . He recognized the benefits of research into poker as a model for decision-making with partial information. However, much of the applicability of his work to ours is lost due to differing goals; rather than being concerned about producing a high performance poker program, he focused on simulating the thought processes of human players. Hence, to achieve this, instead of relying heavily on mathematical analysis, his approach was largely based on modeling human cognitive processes. He did not produce a strong poker player.
