“…The diversity, measured in terms of the Euclidean distance from the other individuals, is used in the ranking procedure thanks to a nondominated sorting of (i) the diversity and (ii) the ranks scored with respect to the objectives of the original MOOP. In [53,54] instead the diversity is used as an additional objective, increasing the dimensionality of the original MOOP. • Other methods: additional methods are available in literature like multiploidy [55], DCGA (diversity control oriented GA) [56], CSGA (complementary surrogate GA) [57], TMPGA (Tabu multi parent GA) [58], FUSS (fitness uniform selection scheme) [59] and other strategies not cited here.…”
