  Many research works have been carried out recently to find the optimal path
in network routing. Among them the evolutionary algorithms is an area where
work is carried out extensively. We in this paper, have used PSO for finding
the optimal path and the concept of region based network is introduced along
with the use of indirect encoding. A comparative study of genetic algorithm
(GA) and particle swarm optimization (PSO) is carried out, and it was found
that PSO performed better than GA.
