In Balas and Niehaus (1996), we have developed a heuristic for generat
ing large cliques in an arbitrary graph, by repeatedly taking two cliq
ues and finding a maximum clique in the subgraph induced by the union
of their vertex sets, an operation executable in polynomial time throu
gh bipartite matching in the complement of the subgraph. Aggarwal, Orl
in and Tai (1997) recognized that the latter operation can be embedded
into the framework of a genetic algorithm as an optimized crossover o
peration. Inspired by their approach, we examine variations of each el
ement of the genetic algorithm-selection, population replacement and m
utation-and develop a steady-state genetic algorithm that performs bet
ter than its competitors on most problems.
