A Deep Dive into Effects of Structural Bias on CMA-ES Performance along Affine Trajectories

no code implementations26 Apr 2024 Niki van Stein, Sarah L. Thomson, Anna V. Kononova

To guide the design of better iterative optimisation heuristics, it is imperative to understand how inherent structural biases within algorithm components affect the performance on a wide variety of search landscapes.
