A new algorithm, Nondominated Sorting Genetic Algorithm (NSGA), is presented in this paper based on Goldberg's suggestion (=-=Goldberg 1989-=-). This algorithm eliminates the bias in VEGA and thereby distributes the population over the entire Pareto-optimal regions.

Although there exist two other implementations (=-=Fonesca and Fleming 1993-=-; Horn, Nafpliotis, and Goldberg 1994) based on this idea, NSGA is different from their working principles, as explained below.

The first practical algorithm, called Vector Evaluated Genetic Algorithm (VEGA), was developed by Schaffer in 1984 (=-=Schaffer 1984-=-). One of the problems with VEGA, as realized by Schaffer himself, is its bias towards some Pareto-optimal solutions. Later, Goldberg suggested a nondominated sorting procedure to overcome this weakne... |

As discussed elsewhere (=-=Goldberg and Deb, 1991-=-), this type of blocked fitness assignment is likely to produce a large selection pressure which might cause premature convergence. MOGA also uses a niche-formation method to distribute the population... |
