In this paper, we propose an approach based on the use of artificial fish swarm algorithm (AFSA) for solving the problem of multicast routing on application layer. Taking delay, stretch, and degree as three optimization objectives, we design the behaviors of artificial fish individual (AF), i.e. moving randomly, preying, following, and use Pareto ranking to evaluate the fitness of AF. The simulation...
This paper presents an artificial fish swarm algorithm for solving Steiner tree problem. A novel encoding method of avoiding the loop generation for artificial fish representation of tree-structure and the operator of behaviors of artificial fish for searching optimal solution of Steiner tree problem are proposed. Simulation experiments have been carried out on different network topologies for networks...
