Genetic algorithms (GAs) is a powerful stochastic search techniques that is used successfully to solve problems in various disciplines like business, engineering, and science, with various degrees of complexity. In many complex optimization / search problems, (i.e., specifically intractable and multi-modal case) GAs can obtain optimal solution in tolerable time. Most of the problems of Knowledge Discovery in Database (KDD) and Data mining (DM) are NP-Complete, trapped by multiple local optima, and often multi-objective in nature. Therefore, GAs can be choosen as a suitable tool to solve the...
