# Within the Letter of the Law: Open-Textured Planning

## Abstract

Most case-based reasoning systems have used a single "best " or "most similar" case as the basis for a solution . For many problems, however , th ere is no single exact solution . Rather, there is a range of acceptable answers. We use cases not only as a basis for a solution, but also to indicate the boundaries within which a solution can be found . We solve problems by choosing some point within those boundaries. In this paper , I discuss this use of cases with illustrations from CHIRON, a system I have implemented in the domain of personal income tax planning.
