Approximation in multiobjective optimization

  • Bernard Lemaire


Some results of approximation type for multiobjective optimization problems with a finite number of objective functions are presented. Namely, for a sequence of multiobjective optimization problems P n which converges in a suitable sense to a limit problem P, properties of the sequence of approximate Pareto efficient sets of the P n 's, are studied with respect to the Pareto efficient set of P. The exterior penalty method as well as the variational approximation method appear to be particular cases of this framework.
