Reformulating mixed-integer quadratically constrained quadratic programs [PDF]

open access: yes, 2011
It is well known that semidefinite programming (SDP) can be used to derive useful relaxations for a variety of optimisation problems. Moreover, in the particular case of mixed-integer quadratic programs, SDP has been used to reformulate problems, rather ...

Transformation of propositional calculus statements into integer and mixed integer programs: An approach towards automatic reformulation [PDF]

open access: yes, 1990
A systematic procedure for transforming a set of logical statements or logical conditions imposed on a model into an Integer Linear Progamming (ILP) formulation Mixed Integer Programming (MIP) formulation is presented. An ILP stated as a system of linear

A Hybrid IP/GA Approach to the Parallel Production Lines Scheduling Problem

open access: yesDiscrete Dynamics in Nature and Society, 2016
A special parallel production lines scheduling problem is studied in this paper. Considering the time window and technical constraints, a mixed integer linear programming (MILP) model is formulated for the problem.

Mixed-Integer Programming to Solve Distribution Problems

open access: yesJournal of New Results in Science, 2020
Mixed-integer linear and quadratic programming problems are considered to solve distribution problems in this paper. The first problem is the distribution of proctors with respect to the student placements to the class- rooms by mixed-integer linear ...

Performance Variability in Mixed-Integer Programming [PDF]

open access: yes, 2013
The performance of mixed-integer programming solvers is subject to some unexpected variability that appears, for example, when changing from one computing platform to another, when permuting rows and/or columns of a model, when adding seemingly neutral changes to the solution process, etc.

Pseudo basic steps: bound improvement guarantees from Lagrangian decomposition in convex disjunctive programming

open access: yesEURO Journal on Computational Optimization, 2018
An elementary, but fundamental, operation in disjunctive programming is a basic step, which is the intersection of two disjunctions to form a new disjunction.

Conflict-Driven Heuristics for Mixed Integer Programming [PDF]

open access: yesINFORMS Journal on Computing, 2020
Two essential ingredients of modern mixed-integer programming solvers are diving heuristics, which simulate a partial depth-first search in a branch-and-bound tree, and conflict analysis, which learns valid constraints from infeasible subproblems.
