Document Summary

Last class defined problem space with a goal, constraints and operators. The gps is a computer simulation to model well-defined problem solving. The gps uses the means-end analysis heuristic. Recent simulations: alpha-go: considered the ultimate goal and follow production rules to get closer to it, these rules can create sub-goals, verified by think-aloud protocols. A computer program that beat the world champion at the game of go: a very complex and ill-defined game of strategy. Alpha-go was not given instructions to learn the game, but shown examples: it developed its own strategies in under 40 days (faster than any human could, a major sign of creativity. Experts define, view and encode a problem in their area of expertise differently than novices. There are functional differences in the brains of experts. What makes an expert: the practice debate, the 10,000-hour (10 year) rule. A mental slip which can lead to faulty decisions .
