A strategy for dynamic battlefield frequency assignment based on discrete particle swarm optimization

For the dynamic battlefield frequency assignment problem, a mathematical mod el is proposed to minimize frequency conflict grade. Then, a Discrete Particle S warm Optimization Algorithm (DPSO) is designed to solve the model, in which particle encoding and swarm cross are conducted. The inbuilt adaption function and the local search policies are carefully designed a ccording to the characters of the model. Simulation results show that the propo sed algorithm can solve frequency assignment problem effectively.
