Graph theory matching
WebDec 3, 2024 · Prerequisite – Graph Theory Basics – Set 1 A graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense “related”. The objects of the graph correspond to … Webmatching pairs constitute the individual nodes of the association graph. The association graph shows the relationship between the potential correspondence pairs and enables the determination of the largest correspondence set. Let the association graph G = (N,E) be an undirected and unweighted graph, where N={n ij, i [1, ,N 1], ,j [1, ,N 2]}
