Real-world design optimization problems are typically computationally-expensive and to address this various model-assisted evolutionary frameworks have been proposed. However, often such problems are also high-dimensional and in such settings models tend to have poor accuracy and thus degrade the optimization search. To address this we propose two complementary dimensionality-reduction frameworks...
This paper presents a study for using Kriging metamodeling in combination with Covariance Matrix Adaptation Evolution Strategies (CMA-ES) to find robust solutions. A general, archive based, framework is proposed for integrating Kriging within CMA-ES, including a method to utilize the covariance matrix of the CMA-ES in a straightforward way to improve the accuracy of the Kriging predictions without...
Optimisation of vehicle schedule with time windows is discussed in this paper. The problem is based on the description and data of a real-life problem. Simulation-based optimisation is used in the search of an optimal solution in this paper. A simulation model is developed for the reviewed vehicles scheduling problem. Two scenarios of optimisation are described. The first scenario involves the use...
