Abstract

Current default rules for operator tie impasses in Soar are examined in relation to known constraints on human memory and real-time requirements imposed on human behavior in dynamic environments. The analysis shows that an alternative approach is required for resolving such impasses, which does not ignore these constraints. As such, this objective is not new. Newell (1990) advocated that the “single state principle” be used in all impasse handling to reduce the “computational cost” associated with it. While the current version of Soar is based on this principle, the default rules for ties still do not satisfy the constraints in question. This paper explores alternative sets of rules that appear promising in meeting them.
