Diameter of undirected graph
WebApr 16, 2024 · 4.1 Undirected Graphs. Graphs. A graph is a set of vertices and a collection of edges that each connect a pair of vertices. We use the names 0 through V-1 for the vertices in a V-vertex graph. Glossary. … 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 …

Webjan graphs. By replacing each undirected edge by two directed edges of opposite directions, the associated directed Ramanujan graph has the same eigenvalues. Corollary 1 yields an upper bound within a factor of 4 of the bound for the undirected case. We have now seen that the eigenvalues of the Laplacian can be used to control the diameter of ...

WebApr 1, 2024 · An orientation of an undirected graph G is an assignment of exactly one direction to each edge of G. The oriented diameter of a graph G is the smallest diameter among all the orientations of G. WebThe first line contains three space-separated integers n, q and w ( 2 ≤ n ≤ 100, 000, 1 ≤ q ≤ 100, 000, 1 ≤ w ≤ 20, 000, 000, 000, 000) – the number of vertices in the tree, the number of updates and the limit on the weights of edges. The vertices are numbered 1 through n. Next, n − 1 lines describing the initial tree follow.

WebCould anybody kindly tell me something about fast calculating radius and/or diameter of non-weighted undirected graph (definitions can be found here) ? Fast = faster, than in O(MN) (breadth-first searches from each vertex). Any results are welcome: probabilistic, good in average, good for sparse graphs, etc. Thanks. brighton police white helmetsWebIn graph theory, a cop-win graph is an undirected graph on which the pursuer (cop) can always win a pursuit–evasion game against a robber, with the players taking alternating turns in which they can choose to move along an edge of a graph or stay put, until the cop lands on the robber's vertex.
