Which algorithm is better for optimal parameter selection ? Glowworm swarm optimization or particle swarm optimization or hybrid Genetic - PSO algorithm ?
For me GSO is the Gothenburg Symphony Orchestra. I prefer that over any metaheuristics in general, and especially over PSO. ;-)
Seriously though, I would not take the route of implementing a meta-heuristic; it is not elegant, there is very little theory, and it can almost always be beaten by a hard-core mathematical optimization methodology, adapted to the problem. It seems to me to be a waste of resources to take that route.
