The paper answers an open problem introduced by Bezdek and Fodor in 2000. The width of any unit-diameter octagon is shown to be less than or equal to `(\fra...

Current network planning and design methods use the average delay, packet loss and throughput as metrics to optimize the network cost and performance. New...

In IP-over-WDM networks, protection can be offered at the optical layer or at the IP layer. Today, it is well acknowledged that synergies need to be develope...

We present ACRE, an Automatic aspeCt cREator, to use aspect-oriented programming to test multi-platform software programs written in C++. ACRE allows devel...

This paper develops a dynamic risk management model to determine a firm's optimal risk management strategy. This strategy has two elements: first, for low ...

In this paper a new branch-price-and-cut method for a maritime inventory routing problem for one of the world's largest producers of liquefied natural gas (L...

This paper presents the design, implementation, and the first experimental results of an architecture for autonomous demand-side load management (ADSM) syste...

A minimum equicut of an edge-weighted graph is a partition of the nodes of the graph into two sets of equal size such that the sum of the weights of ed...

In this article we study a network design problem that arises in the exploitation of wind energy. We formulate this problem as a mixed integer programming ...

This paper presents a framework to determine optimal maintenance planning of a fleet of complex and independent systems. They are made up of several major co...

The inventory routing problem (IRP) and the production routing problem (PRP) are two difficult problems arising in the planning of integrated supply chains...

Interior-point methods in semi-definite programming (SDP) require the solution of a sequence of linear systems which are used to derive the search directions...

Finding <i>p</i> prototypes by minimizing the sum of the squared distances from a set of points to its closest prototype is a well-studied problem in cluste...

OPAL is a general-purpose system for modeling and solving algorithm optimization problems. OPAL takes an algorithm as input, and as output it suggests para...

Given Cloud Computing geographical distribution on multiple regions, the location of data centers, servers and software components and the way information is...

Implementations of the Simplex method differ only in very specific aspects such as the pivot rule. Similarly, most relaxation methods for mixed-integer ...

Wavelets have been successfully used for nonparametric function estimation, but a major challenge in density and hazard estimation is that the function must ...

Although stochastic programming is probably the most effective frameworks for handling decision problems that involve uncertain variables, it is always a cos...

The problem of coordinating a fleet of vehicles so that all demand points on a territory are serviced and that the workload is most evenly distributed among ...

Our main interest is the prediction of future events for recurrent event processes. We intend to build a Bayesian model, based on sound philosophical princip...
