Yacht For One Or Two

Invited Talk
Lewis & Clark College
Portland, Oregon
May 3, 2001


The solitaire version of the dice game Yahtzee™ has been ``solved'' by several different researchers in the past few years. Most recently this was achieved by starting with a simpler game called Yacht. The code described in this talk solves Yacht in a couple of seconds on a modern computer, leading to a reasonable expectation that the full two-player version of Yacht can be solved in a reasonable amount of time using parallelism, although two-player Yahtzee is still at the limit of current computational capabilities. This talk explains the concepts behind perfect solutions to Yacht-like games, describes the methods and heuristics used to achieve current performance, and estimates the computational costs of various extensions to the current work.
