External Behavior of a Logic Program and Verification of Refactoring
arXiv (Cornell University)(2023)
摘要
Refactoring is modifying a program without changing its external behavior. In this paper, we make the concept of external behavior precise for a simple answer set programming language. Then we describe a proof assistant for the task of verifying that refactoring a program in that language is performed correctly.
