Abstract
With the purpose to solve the degree constrained multicast routing model efficiently
the evolutionary strategy was introduced into heuristic search methods by employing the chromosome as the heuristic information for global searching
and then a hybrid genetic algorithm was proposed.The algorithm not only avoids the difficulty of coding for multicast trees
but also possesses fast convergency and global optimizing capability.Meanwhile
the efficiency of the method is supported by a great number of numerical experiments.
