Play Contest Bot Results


From February 2001 to August 2006, I tested various bridge computer programs on the problems in my play contests (held every even month), and the results are summarized here. This should not be regarded as a rigid scientific test because some factors cannot be equalized (e.g., bidding system understandings, and the exact time allowed to make each play). Programs with adjustable skill levels were tested at the highest setting not to exceed one minute per play.

Overall Standings

This table is ranked by the average of the best four scores in the six most recent play contests. Each contest consisted of six problems scored on a 1-to-10 scale, so the maximum score was always 60. The “Best” column shows the best finish by rank (among bots only) and is used to break ties. Alert! HAL is planning a comeback, so don’t write him off just yet.
