An Effective Implementation of a Direct Spanning Tree Representation in GAs

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 2037)


This paper presents an effective implementation based on predecessor vectors of a genetic algorithm using a direct tree representation. The main operations associated with crossovers and mutations can be achieved in O(d) time, where d is the length of a path. Our approach can avoid usual drawbacks of the fixed linear representations, and provide a framework facilitating the incorporation of problem-specific knowledge into initialization and operators for constrained minimum spanning tree problems.
