We present a topology optimization based on a covariance matrix adaptation-evolution strategy (CMA-ES) and its effectiveness for a multimodal topology optimization problem. Structures are expressed by level set functions optimized by the CMA-ES as design variables and are transformed in a design domain for minimizing a regularized fitness composed of device performance-functions and a structural perimeter. The presented method is applied to the topology optimization for polarization independent optical cloak with structural symmetries about three axes and succeed to obtain an optimal configuration having good cloaking performances.
