Conference Paper Description

In the field of theoretical ecology the term "richness" refers to the number of species present in an ecosystem. By reducing the game of Sudoku to the problem of exact four cover (X4C), then reducing X4C to minimum richness equilibrium (MRE), we show that MRE is in NP-complete. We further reduce MRE to minimum weight linear programming (MWLP) to arrive at a simple, polynomial-time decision process that we demonstrate to be a pretty darn good Sudoku solver!
