Gnu Backgammon and Snowie are both very strong, but in about 15% of responses to the opening roll, they disagree with each other, or with rollouts. Let's continue our survey, using long Gnu Backgammon rollouts as the referee. Again, I won't mention every interesting decision, but if I skip a decision, you can assume that Snowie 3-ply and Gnu 2-ply evaluations agree with long rollouts.
First, something unrelated. I'd like to point out a puzzle which reminded me of backgammon, and of the Rolling Pigs game played at some backgammon tournaments. This is problem #232 from the Project Euler site. This site has programming exercises with mathematical themes. Almost all of the problems require some programming in addition to mathematics.
