An Automated Finite First-Order Model Generator Has Been Developed. the Problem is Viewed as a First-Order Satisfiability Problem. Most Existing Model Generators Reduce the Problem to Propositional Satisfiability by Converting the Input First-Order Clauses into Propositional Clauses. This Generator, Unlike Others, Stores the Input First-Order Clauses and Solves the Problem Directly. It Uses an Exhaustive Backtracking Algorithm with Weight-Based Splitting. a Negative Constraint Propagation is Implemented to Reduce the Number of Decision Points and Thus to Speed Up the Search. © 1997 ACM.
