Model Guided Sampling Optimization (MGSO) was recently proposed as an alternative for Jones’ Krigingbased EGO algorithm for optimization of expensive blackbox functions. Instead of maximizing a chosen criterion (e.g., expected improvement), MGSO samples probability of improvement of the Gaussian process model forming multiple candidates – a whole population of suggested solutions. This paper further develops this algorithm using slice sampling method and continuous local optimization of the Gaussian process model.
