Abstract
For bicriterion optimization involving objective functionsf 1 andf 2 defined on a decision spaceX, a condition is presented under which the Pareto-optimal points can be characterized as solutions of the scalar optimization problems: Minimizef 1(x), subject tof 2(x)≤α,x ∈X, which α ranges over a certain interval. Using this condition, it is shown how the Pareto-optimal points can be so characterized in both convex and nonconvex situations.
