Distributed Genetic Algorithm (DGA) has been used to parallel computing and, Common Object Request Broker Architecture (CORBA) is, popular in software integration. In order to reduce the complexity of DGA software development and to minimize the maintenance costs, DGA software with CORBA and Java (DGAandCORBA) is proposed. The advantages and software architecture of DGAandCORBA are illustrated in detail. China Traveling Salesman Problem (CTSP) has been computed with different parameters and three rules about parameters selections are exposed. It's shown that the solution quality with best-migr...
