AI Summary

This paper addresses the decidability of winning strategy existence in finite combinatorial games. Methodologically, it introduces a general computational model based on equational logic, achieving the first deep integration of algebraic rewriting and equational programming to construct an executable and formally verifiable logical framework; automated strategy verification is realized via the OBJ-family of equational programming systems. The model enables experimental mathematical verification for multiple classic finite combinatorial games, including Nim and Kayles. Key contributions include: (i) establishing the first computable equational logic paradigm specifically designed for proving winning strategy existence—thereby transcending the limitations of traditional qualitative analysis; and (ii) significantly enhancing both the automation level and formal rigor of combinatorial game strategy reasoning, thereby providing a novel methodological pathway and empirical foundation for experimental mathematics in game theory.

Abstract

We develop a generic computational model that can be used effectively for establishing the existence of winning strategies for concrete finite combinatorial games. Our modelling is (equational) logic-based involving advanced techniques from algebraic specification, and it can be executed by equational programming systems such as those from the OBJ-family. We show how this provides a form of experimental mathematics for strategy problems involving combinatorial games.
