Abstract: The improved differential evolution algorithm handling constraint is presented to solve the problem which solving the firepower distribution using the differential evolution algorithm need to determine penalty coefficient artificially so that it increases the complexity of building the model. The method uses three selection criteria based on feasibility to guide the search to the feasible region and adds the integer filed to save the integer result. The case study shows that the method compared with the method using penalty function under the same computing efficiency can get the better optimum value. The method needn’t artificially determine penalty coefficient so that it can decrease the model’s determining complexity and time, and can be applied for firepower distribution.
