WebNeighbourhood (mathematics) A set in the plane is a neighbourhood of a point if a small disc around is contained in. In topology and related areas of mathematics, a neighbourhood (or neighborhood) is one of the basic concepts in a topological space. It is closely related to the concepts of open set and interior. WebIn the paper "On finding bicliques in bipartite graphs: a novel algorithm and its application to the integration of diverse biological data types" the authors propose an improvement to an algorithm, by sorting candidate vertices by "common neighborhood size" (page 8 at left). What is the "common" neighborhood for a single vertex?
