Differential Evolution with Interpolation Based Mutation Operators for Engineering Design Optimization

Pravesh Kumar


Differential evolution (DE) has attracted much attention recently as an effective approach for solving numerical optimization problems which arise in many science and engineering fields. This paper presents two modified mutation schemes of differential evolution algorithm for engineering design optimization problem with constraints. These modified mutation scheme are based on interpolation rules, first scheme is based on Inverse Quadratic Interpolation called IQI-DE and second scheme is based on sequential parabolic interpolation called SPI-DE. The proposed variants are tested on 4 engineering design optimization problems, taken from literature. The results show that the proposed modifications improve the performance of basic DE
