Abstract
This paper studies the relationship between logic programs and term rewriting systems (TRSs). A compositional transform is defined which given a logic program computes a TRS. For a relevant class of logic programs, called Simply Well Moded (SWM), there is a one-to-one correspondence between computed answer substitutions of the logic program and normal forms of the corresponding TRS. Moreover the transform preserves termination, i.e., a logic program terminates iff the corresponding TRS terminates. This transform is refined in such a way that the above results hold for a relevant class of unification free programs containing SWM, the class of Flatly Well Moded (FWM) programs.KeywordsNormal FormLogic ProgramTransition RuleModed ProgramGround TermThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
