The new Evolutionary Computing methodology for multiobjective optimization of water distribution system design, GALAXY (Genetically Adaptive Leaping Algorithm for approXimation and diversitY), has been used on a number of benchmarks available on this site. GALAXY was developed as part of the PhD work by Dr Qi Wang.

This was developed into a paper: Wang, Q., D. A. Savić, and Z. Kapelan (2017), GALAXY: A New Hybrid MOEA for the Optimal Design of Water Distribution Systems, Water Resour. Res., doi:10.1002/2016WR019854. The paper is available here.

The code for the GALAXY algorithm and the brief tutorial can be downloaded from here: GALAXY
