Stabilizing swarm intelligence search via positive feedback resource allocation

A novel Swarm Intelligence method for best-¯t search, Stochastic Diffusion Search, is presented capable of rapid location of the optimal solution in the search space. Population based search mechanisms employed by Swarm Intelligence methods can su®er lack of convergence resulting in ill de¯ned stopping criteria and loss of the best solution. Conversely, as a result of its resource allocation mechanism, the solutions SDS discovers enjoy excellent stability.
