This paper proposes a hybrid method using the SIMP (Solid Isotropic Material with Penalization) and IESO (Improved Evolutionary Structural Optimization) methods. In this method, the SIMP method adds to the IESO method’s solution that it is locally optimal. On the other hand, the IESO method adds solution diversity to the SIMP method. The effectiveness of the proposed method is demonstrated by comparing it with the SIMP method using density filtering and the IESO method using sensitivity filtering.
