Relaxation and Decomposition Methods for Mixed Integer Nonlinear Programming

This e-book offers a finished description of concept, algorithms and software program for fixing nonconvex combined integer nonlinear courses (MINLP). the focus is on deterministic international optimization equipment, which play an important position in integer linear programming, and are used only in the near past in MINLP.

1 several methods for solving dual problems based on evaluating the dual function D are studied. e. 8) can be solved fast. 7) is block-separable. 8) decomposes into several subproblems, which typically can be solved relatively fast. 4 Dual-equivalent convex relaxations In the following, several convex relaxations are studied that are equivalent to a related dual problem. Furthermore, it is shown that dual relaxations are stronger than convex underestimating-relaxations. t. h0 (x) hi (x) ≤ 0, i = 1, .

It was presented in (Everett, 1963) for resource allocation problems. The reader is referred to (Geoﬀrion, 1974) and (Lemaréchal, 2001) for an introduction into this ﬁeld. A comprehensive overview on duality theory is given in (Rockafellar and Wets, 1997). The presented theory forms the background for the computation of a relaxation, which is the main tool in relaxation-based MINLP solution methods (see Chapters 11, 12 and 13). 1 Convexiﬁcation of sets and functions The following deﬁnitions and results on the convexiﬁcation of sets and functions will be used in the subsequent sections.

T. Ê f (x) Ax + b ≤ 0 xJk ∈ conv(Gk ), k = 1, . . 12) Ê where f : n → is a nonlinear convex function that is not block-separable. t. f (x) Ax + b ≤ 0 aT xJk ≤ a, x ∈ [x, x] (a, a) ∈ Nkj , k = 1, . . 9). 7. t. 14) k = 1, . . , p by producing inner and outer approximations of conv(Gk ). This technique has three main advantages: (i) It is possible to ﬁx Lagrangian subproblems that are ‘explored’; (ii) It is possible to work with near-optimal solutions of Lagrangian subproblems; (iii) It is easy to update relaxations after branching operations in branch-cut-and-price algorithms.
