This paper presents a topology optimization based on a covariance matrix adaptation evolution strategy (CMA-ES) for acoustic cloaks rendering a scattering object acoustically invisible. The cloaks are designed by minimizing the scattering of acoustic waves around the object and the objective function is defined as the integrated intensity of the scattered wave. CMA-ES is employed to s... https://parisnaturalfoodes.shop/product-category/gastro-assist/
