Rotation Invariance and Rotated Problems: An Experimental Study on Differential Evolution
This paper presents an experimental study on the efficacy of a rotation-invariant Differential Evolution (based on current-to-rand mutation) on a benchmark of test problems in its non-rotated and rotated version. Numerical ...
HyperSPAM: A study on hyper-heuristic coordination strategies in the continuous domain
This article proposes a simplistic algorithmic framework, namely hyperSPAM, composed of three search algorithms for addressing continuous optimisation problems. The Covariance Matrix Adaptation Evolution Strategy (CMAES) ...
A Study on Rotation Invariance in Differential Evolution
Epistasis is the correlation between the variables of a function and is a challenge often posed by real-world optimisation problems. Synthetic benchmark problems simulate a highly epistatic problem by performing a so-called ...
