I am working on multi colony ant algorithm. I need the code for query optimization. Please send any details you have for multi colony ant optimization algorithm.

Ant Colony Optimization (ACO) are a set of probabilistic metaheuristics and an intelligent optimization algorithms, inspired by social behavior of ants. ACO algorithms are also categorized as Swarm Intelligence methods, because of implementation of this paradigm, via simulation of ants behavior in the structure of these algorithms.
