| Abstract: | Aiming to the characteristics of mixed-integer nonlinear programming (MINP), a rounding operation was added to the mutation operator of differential evolution algorithm, a modified differential evolution (MDE) algorithm fitted to the MINP is proposed. At the same time, the method of time-varying crossover probability factor was adopted to improve the global searching ability and convergence speed of MDE. The experiments researching were done by four classic testing functions. The experiment results show that the MDE has fast convergence speed, high precision and good robustness for solving MINP. |
