Table of Contents
This page presents a collection of links and papers related to the hypervolume quality indicator, a measure often used to assess the performance of multi-objective evolutionary algorithms. It is also used directly inside EAs to provide a selection pressure rewarding convergence as well as objective-space diversity of the candidate solutions. Hypervolume has the drawback that it takes exponential time in the number of dimensions to compute. For this reason, there is an active community developing faster algorithms (in theory and in practice) for this important problem.
- PyGMO library: Python wrapper of PaGMO
- Python version by Simon Wessing is a reimplementation of the code by Fonseca et al. (Variant 3, Version 1.2) in pure Python. Some small modifications have been applied to obtain more performance on the Python interpreter.
# usage example: from hv import HyperVolume referencePoint = [2, 2, 2] hyperVolume = HyperVolume(referencePoint) front = [[1, 0, 1], [0, 1, 0]] result = hyperVolume.compute(front)
- R version by Olaf Mersmann
- In The Hypervolume Indicator Revisited: On the Design of Pareto-compliant Indicators Via Weighted Integration (E. Zitzler, D. Brockhoff, and L. Thiele. In S. Obayashi et al., editors, Conference on Evolutionary Multi-Criterion Optimization (EMO 2007), volume 4403 of LNCS, pages 862–876, Berlin, 2007. Springer), the so-called weighted hypervolume indicator has been introduced in order to incorporate specific user preferences into the search.
- The C version implementations of three different bi-objective hypervolume based indicators mentioned in the above paper which incorporate the following preferences: (i) focus on extreme points, (ii) focus on the extremes of the second objective plus one additional extreme point for the first objective, (iii) focus on a given reference point
The S-Metric Selection Evolutionary Multiobjective Optmization Algorithm uses the hypervolume indicator to compute the exclusive hypervolume contribution of solutions.
