Abstract

This article has three objectives: (1) Promote Mace4, a program developed by Bill McCune that searches for finite models of first-order formulas and that is the best way to remember Bill. (2) Promote the research on model generation of first-order formulas. Mace4 remains one of the best model generation programs and we need newcomers who can take over Bill's torch, because model generation is very important to automated reasoning and has many applications. (3) Compare Mace4 with SEM in detail so that the users of these tools or new model generator developers will understand the strengths and weaknesses of both systems and take advantage from this study.
