%X Network coding can improve the bandwidth utilization for multi-source optical multicast, but it increases optical storage and computation overhead in wavelengeh division multi-plexing networks. An improved adaptive genetic algorithm (IAGA) is proposed to minimize the number of optical network coding links for multicast. By designing the maximization difference crossover operation, IAGA can guarantee the diversity of population and avoid from falling into a local optimal. By adaptive adjusting the crossover probability, IAGA makes the population diverse at the beginning stages and makes the excellent individuals remain in a stable condition. Compared with other algorithms, the simulation results show that the proposed algorithm has fastest convergence speed, which means that it takes the shortest time to find the minimum numbers of optical coding link solutions.
