This talk is going to be about the paper "Two-dimensional Subset Selection for Hypervolume and Epsilon-Indicator" by K.Bringmann, T. Friedrich and P. Klitzke accepted at this years GECCO (http://docs.theinf.uni-jena.de/paper/2014GECCO.pdf). The first part of the talk will explain the main tricks of the two algorithms (including the so called convex hull trick). The second part will include some experiments that confirm the results and show some applications.
