WebThe idea behind the formulation of Moore neighborhood is to find the contour of a given graph. This idea was a great challenge for most analysts of the 18th century, and as a result an algorithm was derived from the Moore graph which was later called the Moore Neighborhood algorithm. The pseudocode for the Moore-Neighbor tracing algorithm is 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
