(I'll probably have to go back through it to make sure there's nothing too embarassing) I don't think there's much out there otherwise. The algorithm itself is quite simple. (http://en.wikipedia.org/wiki/Particle_swarm_optimization) Consider coding it yourself if you like. Let me know. ------horndude77 Maybe this would be a good ruby quiz?
