WebFeb 28, 2024 · 1 Answer. Sorted by: 1. If you can iterate effectively over your neighbors, you could say the complexity of your algorithm is even better, namely O ( deg ( S) + deg ( T)). If not, you can still bound it by O ( V) unless you have a multigraph. There might be better algorithms with regard to memory, because your algorithm requires O ( deg ( S ... 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 fnb flowers
