Abstract. This paper furthers the recent investigation of search heuristics based on solution counting information, by proposing and evaluating algorithms to compute solution densi...
This paper describes a Global Computing (GC) environment, called XtremWeb-CH (XWCH). XWCH is an improved version of a GC tool called XtremWeb (XW). XWCH tries to enrich XW in orde...
Abstract. This paper presents a new semantic relatedness measure on semantic networks (SN) that uses both hierarchical and non-hierarchical relations. Our approach relies on two as...
A fundamental problem related to graph structured databases is searching for substructures. One issue with respect to optimizing such searches is the ability to estimate the freque...
