Valid Inequality Based Lower Bounds for WCSP

2007
Most of efficient WCSP solving methods are based on arc consistency notion used to transform a WCSP into an equivalent one easier to solve. There are several forms of arc consistency : AC* [9], DAC* [8], FDAC* [8], EDAC* [4]. Recently, an Optimal Soft Arc Consistency (OSAC) was proposed [2].

Lot-Sizing with Constant Batches: Formulation and Valid Inequalities

Mathematics of Operations Research, 1993
We consider the classical lot-sizing problem with constant production capacities (LCC) and a variant in which the capacity in each period is an integer multiple of some basic batch size (LCB). We first show that the classical dynamic program for LCC simplifies for LCB leading to an O(n2 min{n, C}) algorithm (where n is the number of periods and C the

On the validity of the Cauchy–Schwarz inequality for the bracket map [PDF]

open access: possibleGlasnik Matematicki
Due to its properties, the bracket map associated with a dual integrable unitary representation of a locally compact group can be viewed as a certain operator-valued inner product; however, in the non-commutative setting, the Cauchy–Schwarz property for bracket is no longer present in its full strength.

Bilevel Programming and Maximally Violated Valid Inequalities. [PDF]

open access: possible, 2009
In recent years, branch-and-cut algorithms have become firmly established as the most effective method for solving generic mixed integer linear programs (MIPs). Methods for automatically generating inequalities valid for the convex hull of solutions to such MIPs are a critical element of branch-and-cut.
