WebThe employed and onlooker bees need to be equipped with problem-specific perturbative heuristics in order to tackle combinatorial discrete optimization problems. However, there is a large variety of available problem-specific heuristics. In this paper, a hyper-heuristic method, namely a Modified Choice Function (MCF), is applied such that it ... Webof heuristics is evolved, now extended to include three types of low-level heuristics: constructive, perturbative, and noise heuristics. The approach provided competitive results when compared against well- known methods from the literature. 2.3 Heuristic generation methodologies Generative hyper-heuristics are a relatively recent devel- Web1. mar 2024 · As in our previous work, perturbative heuristics are evolved from solution components and basic actions using GE.
