An Optimal Generation Scheduling Approach Based on Linear Relaxation and Mixed Integer Programming

open access: yesIEEE Access, 2020
This paper proposes an optimal generation scheduling approach based on linear relaxation and mixed integer programming, which is used to solve the generation dispatch problem.

Mixed-integer quadratic programming is in NP [PDF]

open access: yesMathematical Programming, 2016
Mixed-integer quadratic programming is the problem of optimizing a quadratic function over points in a polyhedral set where some of the components are restricted to be integral. In this paper, we prove that the decision version of mixed-integer quadratic programming is in NP, thereby showing that it is NP-complete.

A new interactive approach for solving fully fuzzy mixed integer linear programming [PDF]

open access: yesYugoslav Journal of Operations Research, 2020
In this paper, a novel method to solve Fully Fuzzy Mixed Integer Linear Programming (FFMILP) problems is presented. Our method is based on the definition of membership function and a fuzzy interactive technique for solving the classical multiobjective ...

Network Formulations of Mixed-Integer Programs [PDF]

open access: yesMathematics of Operations Research, 2006
We consider mixed-integer sets described by system of linear inequalities in which the constraint matrix A is totally unimodular; the right-hand side is arbitrary vector; and a subset of the variables is required to be integer. We show that the problem of checking nonemptiness of a set of this type is NP-complete, even in the case in which the linear ...

On mixed-integer random convex programs [PDF]

open access: yes2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
We consider a class of mixed-integer optimization problems subject to N randomly drawn convex constraints. We provide explicit bounds on the tails of the probability that the optimal solution found under these N constraints will become infeasible for the next random constraint.

Integer set reduction for stochastic mixed-integer programming

open access: yesComputational Optimization and Applications, 2023
Two-stage stochastic mixed-integer programming (SMIP) problems with general integer variables in the second-stage are generally difficult to solve. This paper develops the theory of integer set reduction for characterizing the subset of the convex hull of feasible integer points of the second-stage subproblem which can be used for solving the SMIP. The

Analyzing Infeasible Mixed-Integer and Integer Linear Programs [PDF]

open access: yesINFORMS Journal on Computing, 1999
Algorithms and computer-based tools for analyzing infeasible linear and nonlinear programs have been developed in recent years, but few such tools exist for infeasible mixed-integer or integer linear programs. One approach that has proven especially useful for infeasible linear programs is the isolation of an Irreducible Infeasible Set of constraints (

Automatic instantiation of a Variable Neighborhood Descent from a Mixed Integer Programming model

open access: yesOperations Research Perspectives, 2017
In this paper we describe the automatic instantiation of a Variable Neighborhood Descent procedure from a Mixed Integer Programming model. We extend a recent approach in which a single neighborhood structure is automatically designed from a Mixed Integer
