MOSA-EA introduced by Xiaoyu Qin and myself is an #evolutionaryalgorithm for hard combinatorial optimisation problems. It builds on a decade of theoretical research on non-elitist, self-adaptive, population-based evolutionary algorithms.
It has excellent performance, particularly on random #MAXSAT and #NKlandscape problem instances.
