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 ...

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.
