REM (Reduce Elan Machine): Core of the New ELAN Compiler
Résumé
ELAN is a powerful language and environment for specifying and prototyping deduction systems in a language based on rewrite rules controlled by strategies. It offers a natural and simple logical framework for the combination of the computation and deduction paradigms. It supports the design of theorem provers, logic programming languages, constraint solvers and decision procedures. ELAN takes from functional programming the concept of abstract data types and the function evaluation principle based on rewriting.
