Differential evolution (DE) is a simple and powerful population-based evolutionary algorithm, successfully used in various scientific and engineering fields. Although DE has been studied by many researchers, the neighborhood and direction information is not fully and simultaneously exploited in the designing of DE. In order to alleviate this drawback and(More)
Differential evolution (DE) is a simple and powerful population-based evolutionary algorithm. The salient feature of DE lies in its mutation mechanism. Generally, the parents in the mutation operator of DE are randomly selected from the population. Hence, all vectors are equally likely to be selected as parents without selective pressure at all.(More)
Satellite communications technology leads to an important improvement in our life and world. The frequency assignment problem (FAP) is a fundamental problem in satellite communication system for providing highquality transmissions. The whole goal of the FAP in satellite communication system is to minimize co-channel interference between two satellite(More)
