Traditional expert systems deal with problems whose descriptions do not change in the course of problem solving. In the monitoring of dynamic processes, however, this assumption is violated.

Analogical reasoning is an important mode of intelligent problem solving. Here, the authors describe a computational model of finding relevant analogs in memory based on three kinds of constraints.

Discovery of patterns in data usually requires a metric for measuring closeness of individual data points to a proposed...
