Multi-population-based bio-inspired computation may use migration among groups to increase the search diversity. Through good solutions exchanged among sub-populations, better solutions may be found with a high probability. In this paper, we propose two algorithms to dynamically adjust the two primary parameters, migration interval and migration rate, for flexibly reflect solution situation for effective...
In this paper, the sub-ant-colony scheme is revisited to improve the solution quality of the ant colony system. In the scheme, an original ant colony is divided into several sub-ant-colonies, and each sub-ant-colony individually works for its local optimal solution and the best solution among them is output as the final one. The number of ants in a total ant colony is the same as the sum of the ant...
