Voronoi-based archive sampling for robust optimisation

Abstract: We propose a framework for estimating the quality of solutions in a robust optimisation setting by utilising samples from the search history and using MC sampling to approximate a Voronoi tessellation. This is used to determine a new point in the disturbance neighbourhood of a given solution such that-along with the relevant archived points-they form a well-spread distribution, and is also used to weight the archive points to mitigate any selection bias in the neighbourhood history. Our method performs compara… Show more

“…The LOOCV can detect the uncertain area of landscape and at the same time it might obtain a better solution. The Voronoi diagram, which has been demonstrated to be effective in robust optimization [21], provides a promising area for local search in the proposed algorithm. The detail of the proposed framework will be introduced in the next section.…”
