In this paper, we present the PolyMAX module which enhances ns-2 (network simulator 2), the most popular network simulator used in academia, to provide one o...

Finding communities, or clusters, or modules, in networks can be done by optimizing an objective function defined globally and/or by specifying conditions wh...

Clusterwise regression is a clustering technique where multiple lines or hyperplanes are fit to mutually exclusive subsets of a dataset such that the sum of ...

We consider a duopoly competing in quantity, where firms can invest in both innovative and absorptive R&D to reduce their unit production cost, and where t...

We investigate the dynamic effect that the Tandroy's unsustainable practices have on the forest. The Tandroy people lives in Androy, a region located in th...

In 1956, Nordhaus and Gaddum gave lower and upper bounds on the sum and the product of the chromatic number of a graph and its complement, in terms of the or...

It is shown that parametric bootstrap can be used for computing P-values of goodness-of-fit tests of multivariate time series parametric models. These mo...

This paper presents a system architecture for demand side load management in the Smart Grid, which is composed of three main modules for admission control, l...

The Job Grouping Problem consists of assigning a set of jobs, each with a specific set of tool requirements, to machines with a limited tool capacity in orde...

Column generation for solving linear programs with a huge number of variables alternately solves a (restricted) master problem and a pricing subproblem to ad...

The min-max <i>k</i>-vehicles windy rural postman problem consists of minimizing the maximal distance traveled by a vehicle in order to find a set of b...

Modularity maximization is extensively used to detect communities in complex networks. It has been shown however that this method suffers from a resolution l...

We study the problem of packing equal circles in a square from the mathematical programming point of view. We discuss different formulations, we analyse fo...

In a recent paper, Zhan, Zhang, Guan, and Zhou [Phys. Rev. E <b>83</b>, 066120 (2011)] presented a modified adaptive genetic algorithm (MAGA) tailored to the...

Organizational behavior and stakeholder processes continually influence energy strategy choices and decisions. Although theoretical optimizations can provide...

The maximum-stable-set and maximum-clique problems are operations research problems that arise in numerous areas such as social networking, electrical engin...

In the last ten years, finding communities in networks, has been the subject of intense studies. If modularity maximization is still one of the mostly studi...

Finding communities, or clusters, in networks, or graphs, has been the subject of intense studies in the last ten years. The most used criterion for that pu...

Climate change is one of the greatest challenges facing our planet in the foreseeable future and despite the urgency of the situation global GHG emissions ...

The sophisticated and automated means of data collection used by an increasing number of institutions and companies leads to extremely large datasets. Sub...
