A new differential evolution algorithm with a combined mutation strategy

What is it about?

A new differential evolution (DE) algorithm with a combined mutation strategy, termed the CMDE algorithm, is proposed. In the combined mutation strategy the DE/best/1 operator and the DE/current-to-best/1 operator are respectively executed on some superior parents and some mediocre parents, and the DE/rand/1 operator is executed on the other inferior parents. In addition, the individuals participating in the three mutation operators are randomly selected from the entire set of parents. The proposed CMDE algorithm with the three different search modes possesses better population diversity as well as search ability than the classic DE algorithm.

Why is it important?

Effectively and efficiently solve difficult optimization problem, e.g., one-phase path synthesis problems of linkage mechanisms

Comparisons of the performance between the new CMDE algorithm and other well-known quite promising population-based metaheuristic optimization algorithms, such as TLBO and CS will be done in future for some difficult engineering optimization problems. There might be still room for improvements in the performance of CMDE.
