....to row generation in contrast to column generation. The unimodular probing method described in Section 4.3 is such a row generation method. Another form of hybridization based master slave problem concept is Benders decomposition. The idea of Benders decomposition was rst presented in [Ben62] and generalized in [Geo72] Integration of Benders decomposition and constraint programming was described in [EW01] and [Tho01] The classical Benders decomposition is presented below. Consider the linear program P given by; P : min f c i y i subject to G i x A i y i b i 8i (4.6) ....

....MINLP in a Lagrangian formulation and then decomposes it into subproblems in such a way that, after fixing a subset of the variables, the resulting subproblem is convex and can be solved easily. There are three methods to implement this approach. 47 Generalized Benders decomposition (GBD) [67, 77, 29] computes at each iteration an upper bound on the solution sought by solving a primal problem and a lower bound on a master problem. The primal problem corresponds to the original problem with fixed discrete variables, while the master problem is derived through nonlinear duality theory. The ....

....easily. Although these methods may not require the derivatives of continuous subproblems, di#erentiability can help improve solution time and quality. For this reason, we classify these methods under this class. There are three types of these methods. a) Generalized Benders decomposition (GBD) [64, 71, 44] computes at each iteration an upper bound on the solution sought by solving a primal problem and a lower bound on a master problem. The primal problem corresponds to the original problem with fixed discrete variables, whereas master problem is derived through nonlinear duality theory. Its major ....

....have a significantly more (or less) adverse impact on future decisions. We thus need to look at the intrinsic value of each remnant piece and to do this we define a corresponding dual problem. In order to solve the problem we therefore choose a different approach, namely, Benders decomposition [5]. The basic idea is to decompose the problem into hard variables (the integer z variables) and easy variables (the continuous variables) and alternate between solving a linear program and an integer program at each iteration. To apply Benders method, we first consider the above IP but for a ....

....constrained MINLP in a Lagrangian formulation before decomposing it into subproblems in such a way that after 51 fixing a subset of the variables, the resulting subproblem is convex and can be solved easily. There are three classes of these algorithms. a) Generalized Benders Decomposition (GBD) [56, 71, 21] is used to solve a subclass of constrained MINLPs under some convexity assumptions. For example, it requires the continuous subspace to be a nonempty and convex set and the objective and constraint functions to be convex. Its basic idea is to generate in each iteration an upper bound on the ....

....The first stage consists of one inequality which specifies that the total investment cannot exceed the fixed budget. The second stage is an arc chain formulation for maximizing total flow of all commodities. A technique developed by Van Slyke and Wets [1] which in turn is based on Bender s [2] decomposition method, is used. However, it is specialized to exploit the special structure of this problem. The solution technique involves first choosing an arbitrary solution to the first stage constraint. Then the second stage program is solved to obtain an expected value for the objective ....

Although these methods may not require the di#erentiability of functions, derivative information can help improve solution time and quality significantly. There are three types of these methods. 29 Generalized Benders decomposition (GBD) [60, 68, 37] generates in each iteration an upper bound on the solution sought by solving a primal problem and a lower bound on a master problem. The primal problem corresponds to the original problem with fixed discrete variables and provides upper bound information and Lagrange multipliers for each ....

....of the basis inverse. Indirect methods essentially follow the forkjoin protocol, by decomposing the original problem into decoupled first level subproblems and then solving a master coordination problem. Eckstein [27] surveys parallel implementations to date. The Dantzig Wolfe [19] and Benders [7] decomposition are two classic indirect methods. When applied to (CBA) both can be implemented in parallel, since each block can be assigned to a PE. In the fork phase each PE solves the associated subproblem; then, in the join, a PE collects subproblem solution information, partially redefines ....

This research was partially supported by U.S. Oce of Naval Research Grant N0001495 1 0517 and by the Engineering Design Research Center at Carnegie Mellon University, an Engineering Research Center of the National Science Foundation, under grant EEC8943164. Benders decomposition [7, 17] uses a problem solving strategy that can be generalized to a larger context. It assigns some of the variables trial values and nds the best solution consistent with these values. In the process it learns something about the quality of other trial solutions. It uses this information to reduce the ....

....small rectangular bounds. For some specific classes of BMI problems, for example the low order controller design problem, heuristic specialized methods with local convergence have been developed [BG96] The method presented in this paper uses a technique called generalized Benders decomposition [Ben62, Geo72]. It can be interpreted as an extension of the GOP algorithm of Visweswaran and Floudas[FV93, VFIP96] which is a global optimization method for bilinear and biconvex optimization problems. The outline of the paper is as follows. In the next section we present the duality theory, which provides ....
