Automatic Compilation of Logical Specifications into Efficient Programs

  • Donald Cohen

We describe an automatic programmer, or "compiler" which accepts as input a predicate calculus specification of a set to generate or a condition to test, along with a description of the underlying representation of the data. This compiler searches a space of possible algorithms for the one that is expected to be most efficient. We describe the knowledge that is and is not available to this compiler, and its corresponding capabilities and limitations. This compiler is now regularly used to produce large programs.

A Forward Inference Engine to Aid in Understanding Specifications

  • Donald Cohen

An important part of understanding a specification is recognizing the consequences of what is stated. We describe a program that can help a user acquire this understanding. It does this by deriving interesting, though not deep consequences of a set of input axioms, while avoiding (a typically much larger set of) uninteresting consequences. The heuristics for obtaining that effect are described and justified. The program has been used in a symbolic evaluator that helps a user to understand and debug specifications written in the Gist specification language.
