Abstract

How to reuse or adapt past solutions to new problems is one of the least understood problems in case-based reasoning. In this paper we will focus on the problem of how to combine solutions coming from multiple cases in search-based approaches to reuse. For that purpose, we introduce the notion of amalgam. Assuming the solution space can be characterized as a generalization space, an amalgam of two solutions is a third solution which combines as much as possible from the original two solutions. In the paper we define amalgam as a formal operation over terms in a generalization space, and we discuss how amalgams may be applied in search-based reuse techniques to combine case solutions.
