Diversity assignment sheme based on crowding distance proposed in: K.
<p>
Deb, A. Pratap, S. Agarwal, T. Meyarivan, "A Fast and Elitist Multi-Objective Genetic Algorithm: NSGA-II", IEEE Transactions on Evolutionary Computation, vol. 6, no. 2 (2002). Tis strategy assigns diversity values FRONT BY FRONT. It is, for instance, used in NSGA-II.
