Global optimality principles for polynomial optimization over box or bivalent constraints by separable polynomial approximations

Jeyakumar, V.; Li, G.; Srisatkunarajah, S. - In: Journal of Global Optimization 58 (2014) 1, pp. 31-50

In this paper we present necessary conditions for global optimality for polynomial problems with box or bivalent constraints using separable polynomial relaxations. We achieve this by first deriving a numerically checkable characterization of global optimality for separable polynomial problems...
