global optimization, differential evolution, successful-parent selection, experimental comparison, CEC 2014 test suite

Successful-parent selection (SPS) framework in differential evolution (DE) is studied. two SPS versions (SPS1 proposed recently in literature and SPS2 newly proposed in this paper) are applied to seven state-of-the-art DE variants. The algorithms are compared experimentally on CEC 2014 test suite used as a benchmark. The application of SPS1 increases the efficiency of two DE algorithms in over 50 % of test problems. An overall comparison shows that the newly proposed SPS2 performs well only in two cases whereas SPS1 outperforms six out of 7 original algorithms.
