Routing and Wavelength Assignment (RWA) problem in all-optical networks assumes determining the routes and wavelengths to be used to create the lightpaths for connection requests. The RWA problem belongs to a class of difficult combinatorial optimization problems. We propose the Bee Colony...
This paper examines the callgraphs of 120 malicious and 280 non-malicious executables. Pareto models are fitted to indegree, outdegree and basic block count distributions, and a statistically significant difference is shown for the derived power law exponent. A two-step optimization process is...
In this paper we study the potential of gene–protein interaction networks to store input–output patterns. The central question in this study concerns the memory capacity of a network of a given number of genes and proteins, which interact according to a linear state space model with external...
In many applications we are required to locate the most prominent group of vertices in a complex network. Group Betweenness Centrality can be used to evaluate the prominence of a group of vertices. Evaluating the Betweenness of every possible group in order to find the most prominent is not...
Social resource sharing systems like YouTube and del.icio.us have acquired a large number of users within the last few years. They provide rich resources for data analysis, information retrieval, and knowledge discovery applications. A first step towards this end is to gain better insights into...
The clustering coefficient has been used successfully to summarise important features of unweighted, undirected networks across a wide range of applications in complexity science. Recently, a number of authors have extended this concept to the case of networks with non-negatively weighted edges....
