Kriging-guided Level Set Method for Structural Topology Optimization

Crashworthiness optimization problems are characterized by strong nonlinearities and discontinuities. Hence, gradient-based methods cannot be used and alternative approaches have to be considered. Here, a novel, kriging-based method for level set topology optimization is proposed and validated on a crash test case. Compared to CMA-ES, this method demonstrates to be efficient in terms of convergence speed and promising in the context of crash topology optimization.
