Column generation algorithms are instrumental in many areas of applied optimization, where linear programs with an enormous number of columns need to be so...
BibTeX referenceA Continuous Analysis Framework for the Solution of Location-Allocation Problems with Dense Demand
Location-allocation problems arise in several contexts, including supply chain and data mining. In its most common interpretation, the basic problem consists...

The bidline scheduling problem with equity arises in several North American airlines. It consists of determining anonymous monthly schedules, called bidlines...

Upper bounds on the average distance \(\overline{l}\)
between pairs of vertices of a connected graph with given order \(n\)
and minimum degree `(\delta...
The transmission of a vertex in a connected graph is the sum of all distance from that vertex to the others. It is said to be normalized if divided by <i>n-1...

Variable neighborhood search (VNS) is a metaheuristic, or framework for building heuristics, based upon systematic change of neighborhoods both in a decent ...

With the help of the Graffiti system, Fajtlowicz conjectured around 1992 that the average distance between two vertices of a connected graph <i>G</i> is at ...

We consider one of the most important issues for multinationals, the determination of transfer prices. To do so, we examine the example of a multinational co...

This paper describes a class of large-scale capacity planning problems under uncertainty. The uncertainty can arise in different dimensions of a production...

In this paper we present a simple technique that uses background information to improve mining the frequent patterns of structured data. This technique uses ...
BibTeX referenceSyGMA: Reducing Symmetry in Graph Mining
While recent algorithms for mining the frequent subgraphs of a database are efficient in the general case, these algorithms tend to do poorly on databases th...

Flexibility in workforce planning is one of the best ways to respond to fluctuations of the demand. This paper proposes a flexible mixed integer linear pro...

Real-world routing problems are often represented by large and complex models, and instances of realistic size are very hard to solve. In most cases one ca...

This paper describes a new heuristic for the well-known <i>Undirected Rural Postman Problem</i>. It consists of two steps: it first constructs a partial so...

Storage location assignment and interleaving policy are two closely related problems in warehousing management. This paper addresses the location assignmen...
BibTeX referencePath Reduced Costs for Eliminating Arcs
In many branch-and-price algorithms, the column generation pricing problem consists of computing feasible paths in a network. In this paper, we show how, in...
BibTeX referenceCould Myopic Pricing be a Strategic Choice in Marketing Channels? A Game Theoretic Analysis
We identify the conditions under which a myopic pricing behavior could be a profit enhancing tool in the distribution channel. A channel member behaves myo...
