EN Hypervolume subset selection (HSS) is an important problem in evolutionary multiobjective optimization (EMO). It may be used to guide EMO algorithms, to bound Pareto archives, or to select a reduced set of the most representative solutions of a multiobjective problem for further analysis by the decision maker. Lazy greedy incremental and decremental hypervolume subset selection algorithms are currently the fastest approximate methods for more than 4 objectives and moderate sizes of the candidate sets. In this paper, we show that the efficiency of these lazy algorithms could be further improved by adaptive update of previously calculated hypervolume contributions instead of always recalculating the contributions from scratch. We show also that the Improved Quick Hypervolume algorithm is well-suited for such a context because its recursion tree does not depend on dominated points which often appear when hypervolume contributions are updated.
