摘要

Given a specification R, it is common for a candidate program P to be doing more than R requires; this is not necessarily bad, and is often unavoidable, due to programming language constraints or to otherwise sensible design decisions. In this paper, we introduce a relational operator that captures, for a given specification R and candidate program P, the functionality delivered by P that is relevant to R. This operator, which we call the projection of P over R (for reasons we explain), has a number of interesting properties, which we explore in this paper.
