Set intersection problems: supporting hyperplanes and quadratic programming [PDF]

Mathematical Programming, 2014
We study how the supporting hyperplanes produced by the projection process can complement the method of alternating projections and its variants for the convex set intersection problem. For the problem of finding the closest point in the intersection of closed convex sets, we propose an algorithm that, like Dykstra's algorithm, converges strongly in a ...

Coordinated allocation of distributed generation, soft open points and energy storage systems in unbalanced distribution networks considering flexibility deficiency risk

Alexandria Engineering Journal
Optimizing the location and capacity of flexible resources is critical. The increase in the permeability of distributed generation (DG) causes the net load to drastically fluctuate, which sharply increases flexibility demand for the distribution network.

The Bipartite Boolean Quadratic Programming Problem

, 2014
We consider the Bipartite Boolean Quadratic Programming Problem (BQP01), which generalizes the well-known Boolean Quadratic Programming Problem (QP01). The model has applications in graph theory, matrix factorization and bioinformatics, among others. BQP01 is NP-hard.

Primal-Dual Method of Solving Convex Quadratic Programming Problems [PDF]

Computer Science Journal of Moldova, 2000
This paper presents a primal-dual method for solving quadratic programming problems. The method is based on finding an exact solution of a finite sequence of unconstrained quadratic prigraamming problems and on finding an aproximative solution of ...

An unconstrained binary quadratic programming for the maximum independent set problem

Nonlinear Analysis, 2012
For a given graph G = (V, E) the maximum independent set problem is to find the largest subset of pairwise nonadjacent vertices. We propose a new model which is a reformulation of the maximum independent set problem as an unconstrained quadratic binary ...
