integer programming can be modeled as a nonlinear program. We should not be overly optimistic about these formulations, however; later we shall explain why nonlinear programming is not attractive for solving these problems. 13.2 LOCAL vs. GLOBAL OPTIMUM Geometrically, nonlinear programs can behave much differently from linear programs, even for ...

ALPHA-ECP is an MINLP solver based on the extended cutting plane method. The ECP method is an extension of Kelley’s (1960) cutting plane algorithm which was originally given for convex NLP problems. In Westerlund and Pettersson (1995) the method was extended to convex MINLP problems, and in Westerlund et al. (1998) to MINLP problems with f and g ps...
BARON(Branch-and-Reduce Optimization Navigator) is a computational system for the solution of nonconvex optimization problems to global optimality. The solver combines branch-and-bound techniques specialized for nonconvex MINLPs with bound reduction based on both feasibility and optimality reasoning, which improve its performance. It is currently o...
BONMIN (Basic Open-source Nonlinear Mixed INteger programming) is an open-source code for solving MINLP problems. It is distributed within COIN-OR (http://www.coin-or.org) under Common Public License (CPL). There are several algorithmic options that can be selected within BONMIN. B-BB is an NLP-based branch-and-bound algorithm, B-OA is an outer-app...
COUENNE (Convex Over and Under ENvelopes for Nonlinear Estimation) is a spatial branch-and-bound algorithm to solve MINLP problems. COUENNEaims at finding global optima of nonconvex MINLPs. It implements linearization, bound reduction, and branching methods within a branch-and-bound framework. Its main components are: (i) an “expression library”, i...
DICOPT (DIscrete and Continuous OPTimizer) is a software for solving MINLP problems where nonlinearities involve only continuous variables. Binary and integer variables appear only in linear functions. The implementation is based on outer approximation, equality relaxation and augmented penalty, i.e., equality constraints are relaxed obtaining ineq...
FILMINT is a solver for convex MINLPs. It is based on the LP/NLP branch-and-bound algorithm of Quesada and Grossmann (1992). FILMINT combines the MINTO branch-and-cut framework (Nemhauser et al. 1994) for MILP with FILTERSQP used to solve the nonlinear programs that arise as subproblems in the algorithm. The MINTO framework allows one to employ cut...
LAGO (LAgrangian Global Optimizer) is a Branch-and-Cut algorithm to solve MINLPs. A linear outer approximation is constructed from a convex relaxation of the problem. Because LAGO does not have an algebraic representation of the problem, reformulation techniques for the construction of the convex relaxation cannot be applied, and sampling technique...
LINGO is an optimization suite that handles virtually any mathematical programming problem including MINLP. It implements branch-and-cut methods for global optimization but, in case a global solution is computationally too costly (or not ‘needed’), LINGO solution method can be turned into a heuristic that uses special features like multistart techn...
MINLPBB is a package of FORTRAN 77 subroutines for finding solutions to MINLP problems. The package implements the branch-and-bound method in a nonlinear setting. The package must be used in conjunction with FILTERSQP and BQPD (Nocedal and Wright 2006) for solving NLPs. Problems are specified in the same way as for FILTERSQP (i.e., either via subro...
MINOPT is a package that comprehends solvers for virtually any mathematical programming problem including MINLP. Specifically, MINOPT provides implementations of GBD and variants of OA. In addition, the MINOPTalgorithmic framework provides a modeling language and has connections to a number of solvers. In summary: 1. Implemented algorithms: general...

1 day ago · These methods can handle various types of optimization problems, such as quadratic programs (Amos & Kolter, 2017; Sambharya et al., 2023), stochastic optimization (Donti et al., 2017), submodular optimization (Djolonga & Krause, 2017), and even integer linear programs (Wilder et al., 2019; Berthet et al., 2020; Pogančić et al., 2020). In these approaches, optimization algorithms or solvers ...
Nonlinear programming. In mathematics, nonlinear programming (NLP) is the process of solving an optimization problem where some of the constraints are not linear equalities or the objective function is not a linear function. An optimization problem is one of calculation of the extrema (maxima, minima or stationary points) of an objective ...
Summary. Nonlinear programming is a direct extension of linear programming, when we replace linear model functions by nonlinear ones. Numerical algorithms and computer programs are widely applicable and commercially available as black box software.
