Optimality criteria form the foundations of mathematical programming both theoretically and computationally. In general, these criteria can be classified as either necessary or sufficient. Of course, one would like to have the same criterion be both necessary and sufficient. However, this occurs only under somewhat ideal conditions which are rarely satisfied in practice. In the absence of conve...

A substance which shows comparable ontogenetic effects throughout the plant and animal kingdoms is valuable in interpreting certain fundamental growth phenomena. Colchicine is such a compound. Parasorbic acid is another, and is of even greater interest since it exhibits a range of effects far wider than that of colchicine. Parasorbic acid inhibits the growth of Amphibia and mammals (Heaton, 192...

In the preface to The Structure of Scientific Revolutions, Thomas Kuhn cites as unifying many of his studies a problem-structure and orientation including "the way in which the experimental bases of a new theory are accumulated and assimilated by men committed to an incompatible older theory" (SSR p.ix). (1) This phenomenon contributed greatly to the movement in Kuhn's career from physics, to h...

This paper studies bilevel polynomial optimization. We propose a method to solve it globally by using optimization relaxations. Each relaxation is obtained from the Karush--Kuhn--Tucker ...
