Recursive differential grouping
WebFollowing this research idea, this study develops a new decomposition algorithm named recursive differential grouping with local search ability (LS-RDG) by embedding the Solis Wets local search operator into the recently developed RDG algorithm. LS-RDG can obtain more promising solutions without consuming extra fitness evaluations. WebJun 3, 2024 · The state-of-the-art grouping methods, such as differential grouping and recursive differential grouping, are unable to work properly in noisy environments. Because it is impossible to distinguish whether the change of one variable’s difference value is caused by noise or the perturbation of its interacting variables.

Web2) Recursive Differential Grouping: Recursive Differential Grouping (RDG) [14] reduces the complexity of DG2 from O(n2) to O(nlog(n)). DG and DG2 perform the pair-wise interaction check, whereas RDG consider two disjoint groups of variables X1 and X2 that are subsets of X = {x1,...,xn}. Groups interact if at least one pair of variables xp ∈ ... WebRecursive Differential Grouping In this sub-section, we describe the RDG method in detail and discuss the issues of RDG when dealing with overlapping problems. The RDG method identies the interaction between two subsets of variables X1and X2based on a measure of non-linearity detection (see Fig. 2 for an example): Theorem 1.

WebIn this paper, a new algorithm, taking benefit from cooperative coevolution and surrogate models, is introduced to efficiently solve high-dimensional, expensive and black-box problems. The proposed algorithm uses recursive differential grouping to perform an accurate problem decomposition. Webgrouping (RDG) method with a recursive interaction struc-ture. RDG identifies the relationship between a pair of sets of variables in a recursive manner. The computational com-plexity of RDG is O(nlogn), but RDG is inefficient in decomposition on partially separable problems [17]. Based on RDG, the recursive differential grouping with an adap-
