We consider the vertex coloring problem, which may be stated as the problem of minimizing the number of labels that can be assigned to the vertices of a graph G such that each ver...
Abstract To date, trust and reputation systems have often been evaluated using methods of their designers' own devising. Recently, we demonstrated that a number of noteworthy ...
We establish relations between the bandwidth and the treewidth of bounded degree graphs G, and relate these parameters to the size of a separator of G as well as the size of an exp...
The Pathfinder project makes inventive use of relational database technology--originally developed to process data of strictly tabular shape--to construct efficient database-suppo...
In edge colouring it is often useful to have information about the degree distribution of the neighbours of a given vertex. For example, the well known Vizing's Adjacency Lem...
