This is a summary of the most important results presented in the author's PhD thesis (Spanjaard, 2003). This thesis, written in French, was defended on 16 December 2003 and su...
The edge asymmetry of a directed, edge-weighted graph is defined as the maximum ratio of the weight of antiparallel edges in the graph, and can be used as a measure of the heterog...
The revised graph unification algorithms presented here are more efficient because they reduce the amount of copying that was necessary because of the assumption that data-structu...
Abstract. A hybrid genetic algorithm is proposed for the sequential ordering problem. It is known that the performance of a genetic algorithm depends on the survival environment an...
