Detailed Description

template<class MOEOT>
class moeoNSGA< MOEOT >

NSGA (Non-dominated Sorting Genetic Algorithm) as described in: N.

Srinivas, K. Deb, "Multiobjective Optimization Using Nondominated Sorting in Genetic Algorithms". Evolutionary Computation, Vol. 2(3), No 2, pp. 221-248 (1994). This class builds the NSGA algorithm only by using the fine-grained components of the ParadisEO-MOEO framework.
