WebOct 1, 2015 · The neighborhood graph N (G) of a graph G = (V, E) is the graph with the vertex set V∪S where S is the set of all open neighborhood sets of G and with two vertices u, v ∈ V∪S adjacent if u ... Webneighborhood graph search, which constructs a neighbor-hood graph to index the data points and conducts a local search, expanding neighborhoods with a best-first manner, for ANN search. Our empirical analysis shows that neigh-borhood expansion is very efficient, with O(1) cost, for a new NN candidate location, and has high chances to locate true
WebSecond neighborhood problem. In mathematics, the second neighborhood problem is an unsolved problem about oriented graphs posed by Paul Seymour. Intuitively, it suggests that in a social network described by such a graph, someone will have at least as many friends-of-friends as friends. The problem is also known as the second neighborhood ...
