Diameter of undirected graph
WebB. Diameter of Graph. CQXYM wants to create a connected undirected graph with n nodes and m edges, and the diameter of the graph must be strictly less than k − 1. Also, CQXYM doesn't want a graph that contains self-loops or multiple edges (i.e. each edge connects two different vertices and between each pair of vertices there is at most one … WebThe Naive algorithm for finding the diameter of an undirected unweighted graph takes O (nm) time where n is the number of vertices in the given graph and m is the number of …

WebApr 7, 2024 · The breadth-first search (BFS) algorithm is used to search a tree or graph data structure for a node that meets a set of criteria. It starts at the tree’s root or graph and searches/visits all nodes at the current … WebLet G = (V,E) be a graph with vertex set V and edge set E. Throughout this pa-per, we consider simple graphs, i.e. undirected, loopless graphs without multiple edges. Adjacency of vertices v and w will be denoted by v ∼ w and the open and closed neigh-borhood of a vertex v by G(v)and G[v]respectively. The induced subgraph G[S]on a
