Aiming at the problem of multicast routing with multiple QoS constraint
a new genetic algorithm(GA) was brought up based on the simulated annealing(SA) mechanism. The algorithm combined the capability of local optimiza-tion of SA with global optimization of GA
and used of independent evolutionary mechanism of isolation niche. It can effectively enhance the operating efficiency and improve the solution quality. The simulation experiment indicated that
compares with the traditional genetic algorithm
the performance of this algorithm has remarkable improvement.
