Multiswarm-assisted expensive optimization
Web19 ian. 2024 · 2.2. Surrogate-assisted optimization Surrogate-assisted optimisation has been initially motivated by computationally expensive engineering and design prob-lems. Ong et al. [18] proposed parallel evolutionary opti-misation with application to aerodynamic wing design where surrogate models used radial basis functions (RBF) networks. WebThe accuracy of the surrogate models degrades as the number of decision variables increases. In this paper, we propose a surrogate-assisted expensive multi-objective optimization algorithm based on decision space compression. Several surrogate models are built in the lower dimensional compressed space.
