IRSfast: Fast Expected Hypervolume Improvement Calculation.
Fast 2-D and 3-D hypervolume computation (For download click HERE). The source code is based on: Hupkens, I., Deutz, A., Yang, K., & Emmerich, M. (2015, March). Faster Exact Algorithms for Computing Expected Hypervolume Improvement. In Evolutionary Multi-Criterion Optimization (pp. 65-79). Springer International Publishing. It is based on an earlier implementation of the expected hypervolume improvement algorithms first described in the master's thesis of Iris Hupkens, but significantly reduced the number of transcendental function calls. For the thesis of Iris Hupkens (advisors: Dr. Michael Emmerich, Dr. Andre Deutz), August 2013, LIACS, Leiden University, see: http://www.liacs.nl/assets/Masterscripties/2013-12IHupkens.pdf

Hypervolume Contributions for 3-D point sets in Asymptotically Optimal Time O(n log n) (C/C++)
The zip-file hvcon3d.zip provides C++ code that can be used to compute all hypervolume contributions of a 3-D non-dominated point set in asymptotically optimal time O(n log n). It uses the AVL-tree implementation of Daniel Nagy, Budapest University of Technology and Economics. The algorithm is described in the paper:

VMO: Visualization for Multiobjective Optimization (Windows Release)
VMO is a software tool for the visualization of multiobjective optimization data. This software tool is developed by W. Wu and has proven to be a very useful tool for the visualization of Pareto fronts multiobjective optimization. It can be downloaded as a zip-file: VMO_v1.0.zip. To install it, just unzip it and run the executable. A small user manual is included in the zip-file. On request, we can also provide a linux release (e-mail: Michael Emmerich, emmerich-at-liacs-dot-nl).
