Solving unconstrained 0-1 polynomial programs through quadratic convex reformulation [PDF]

open access: yesJournal of Global Optimization, 2021
We propose a solution approach for the problem (P) of minimizing an unconstrained binary polynomial optimization problem. We call this method PQCR (Polynomial Quadratic Convex Reformulation). The resolution is based on a 3-phase method. The first phase consists in reformulating (P) into a quadratic program (QP).

A Convex Reformulation and an Outer Approximation for a Large Class of Binary Quadratic Programs [PDF]

open access: yesOperations Research, 2023
Binary Quadratic Program with Variable Partitioning Constraints The binary quadratic program with variable partitioning constraints is a very general class of optimization problems that is very difficult to solve because of the nonconvexity and integrality of the variables and is ubiquitous, among others, in network design, computer vision, and ...

Exact quadratic convex reformulations of mixed-integer quadratically constrained problems [PDF]

open access: yesMathematical Programming, 2015
This article considers the general mixed integer, quadratically constrained problem in combinatorial optimization and proposes a novel reformulation of the problem into an equivalent quadratic problem with a convex continuous relaxation. The article begins with an overview of the literature and the mathematical formulation of the problem, followed by ...

Quadratic 0–1 programming: Tightening linear or quadratic convex reformulation by use of relaxations [PDF]

open access: yesRAIRO - Operations Research, 2008
Summary: Many combinatorial optimization problems can be formulated as the minimization of a 0-1 quadratic function subject to linear constraints. In this paper, we are interested in the exact solution of this problem through a two-phase general scheme.

Quadratic Convex Reformulations for Semicontinuous Quadratic Programming [PDF]

open access: yesSIAM Journal on Optimization, 2017
Summary: We consider in this paper a class of semicontinuous quadratic programming problems, which arises in many real-world applications such as production planning, portfolio selection, and subset selection in regression. We build upon the idea of the quadratic convex reformulation approach, i.e., adding to the original objective function an ...

Using a Conic Bundle Method to Accelerate Both Phases of a Quadratic Convex Reformulation [PDF]

open access: yesINFORMS Journal on Computing, 2017
We present algorithm MIQCR-CB that is an advancement of MIQCR. MIQCR is a method for solving mixed-integer quadratic programs and works in two phases: the first phase determines an equivalent quadratic formulation with a convex objective function by solving a semidefinite problem (SDP); in the second phase, the equivalent formulation is solved by a ...

Solving a general mixed-integer quadratic problem through convex reformulation : a computational study [PDF]

open access: yes, 2010
Abstract. Let (QP) be a mixed integer quadratic program that consists of minimizing a quadratic function subject to linear constraints. In this paper, we present a convex reformulation of (QP), i.e. we reformulate (QP) into an equivalent program, with a convex objective function.
