WebA popular measure of the quality of an approximated Pareto front is the front’s hypervolume (Zitzler and Thiele, 1998), which measures the size of the space enclosed by all solutions on the Pareto front and a user-defined reference point (for a formal definition see Section 2). Webarxiv.org WebA measure that has been the subject of much recent study in evolutionary multi-objective optimization is the hypervolume indicator. It measures the volume of the dominated portion of the objective space and is of exceptional interest as it possesses the highly desirable feature of strict Pareto compliance.

WebApr 13, 2024 · The Pareto dominance performs worse with increasing dimensionality, which results in a many -objective optimizations problem (MaOO). The main attribute of the problem is the curse of dimensionality. A possible solution is to use dimensionality reduction to reduce the number of objectives and enable the successful application of Pareto fronts.

WebThe basic idea is to specify the reference point so that a set of well-distributed solutions over the entire linear Pareto front has a large hypervolume and all solutions in such a solution set have similar hypervolume contributions.
