An Empirical Evaluation of the Utility of Case Failure Analysis

 A preliminary study was conducted with the aim of demonstrating the advantage of storing and retrieving cases on the basis of experienced retrieval failure. Domains were chosen in which randomly generated problems contained negatively interacting goals, and planning performance was tested when DERSNLP+EBL was solving multi-goal problems from scratch and through replay of single cases covering a smaller subset of goals. Replay performance was tested both with and without case failure information.
