Interest in constrained optimization originated with the simple linear pro gramming model since it was practical and perhaps the only computationally tractable

Many engineering, operations, and scientific applications include a mixture of discrete and continuous decision variables and nonlinear relationships involving

Disjunctive Programming is a technique and a discipline initiated by the author in the early 1970's, which has become a central tool for solving nonconvex optim

Nonlinearoptimizationproblemscontainingbothcontinuousanddiscretevariables are called mixed integer nonlinear programs (MINLP). Such problems arise in many ?elds

Optimization models based on a nonlinear systems description often possess multiple local optima. The objective of Global Optimization (GO) is to find the best
