A Novel Evolution Strategy with Directional Gaussian Smoothing for Blackbox Optimization

7 Feb 2020Jiaxin ZhangHoang TranDan LuGuannan Zhang

We propose an improved evolution strategy (ES) using a novel nonlocal gradient operator for high-dimensional black-box optimization. Standard ES methods with $d$-dimensional Gaussian smoothing suffer from the curse of dimensionality due to the high variance of Monte Carlo (MC) based gradient estimators... (read more)
