MACE is a program that searches for finite models of first-order statements.
The statement to be modeled is first translated to clauses, then to relational
clauses; finally for the given domain size, the ground instances are
constructed. A Davis-Putnam-Loveland-Logeman procedure decides the
propositional problem, and any models found are translated to first-order
models. MACE is a useful complement to the theorem prover Otter, with Otter
searching for proofs and MACE looking for countermodels.Comment: 10 page
