Bee System: finding solution by a concentrated search

We propose an improved genetic algorithm named Bee System. The concept of the Bee System comes from the behavior of bees: first, a bee finds feed and then it notifies this information to the other bees by a dance to work together. In the proposed Bee System, each chromosome tries to find a good solution individually. When some chromosome is regarded as superior one, other chromosomes try to find a solution around there using multiple populations. Such a procedure is then repeated. The Bee System employs some new operations such as concentrated crossover, and Pseudo-Simplex Method. By computer simulations it is confirmed that the Bee System has better performance than the conventional genetic algorithm.
