On a pair of nonlinear mixed integer programming problems

European Journal of Operational Research, 1985
Let \(M\subset {\mathbb{R}}^ n\times {\mathbb{R}}^ m\) be an open set containing \(S\times T\), where \(S=U\times C_ 1\), \(T=V\times C_ 2\) and K:M\(\to R\) is a twice continuously differentiable function. It is assumed that the first \(n_ 1\) components of n and the first \(m_ 1\) components of y \((0\leq n_ 1\leq n\); \(0\leq m_ 1\leq m)\) are ...

Nonlinear and Mixed Integer Linear Programming

2012
In this chapter we compare continuous nonlinear optimization with mixed integer optimization of water supply networks by means of a meso scaled network instance. We introduce a heuristic approach, which handles discrete decisions arising in water supply network optimization through penalization using nonlinear programming.

An Approximate Algorithm for the Mixed Integer Nonlinear Programming

2012 Fifth International Joint Conference on Computational Sciences and Optimization, 2012
An algorithm for global optima of general mixed integer nonlinear programming (MINLP) is proposed in this paper. The mixed local minimizer of MINLP is first defined, and then a mixed steepest descent algorithm is proposed for the mixed local minimizer. Motivated by some auxiliary function algorithm for continuous global optimization, such as the filled

Heterogeneous parallel method for mixed integer nonlinear programming

Computers & Chemical Engineering, 2014
Abstract In a heterogeneous parallel structure, two types of algorithms, Quesada Grossmann's (QG) algorithm and Tabu search (TS), are used to solve mixed integer nonlinear programming (MINLP) simultaneously. Communication is well designed between two threads running the two algorithms individually by exchanging three kinds of information during ...

A Mixed-Integer Nonlinear Program for the Design of Gearboxes

2017
Gearboxes are mechanical transmission systems that provide speed and torque conversions from a rotating power source. Being a central element of the drive train, they are relevant for the efficiency and durability of motor vehicles. In this work, we present a new approach for gearbox design: Modeling the design problem as a mixed-integer nonlinear ...
