Retrieval, reuse, and retention in CBR

Case-base reasoning (CBR) is an approach to problem solving that emphasizes the role of prior experience during future problem solving: new problems are solved by reusing the solutions to similar problems that have been solved in the past. To date CBR has enjoyed considerable 2 R. LÓPEZ DE MÁNTARAS ET AL. success in a wide variety of problem solving tasks and domains. In this paper, following a brief overview of the traditional problem-solving cycle in case-based reasoning, we examine the cognitive science foundations of CBR and the relationship between CBR and analogical reasoning. We then go on to review a representative selection of CBR research on aspects o
