**How to find all vertices reachable from a start vertex**

Graph Theory 1 De ning and representing graphs A graph is an ordered pair G= (V;E), where V is a nite, non-empty set of objects called vertices, and Eis a (possibly empty) set of unordered pairs of... (a) Show that G contains a path of length at least 2k 1. (b) For each k 1, give an example of a graph in which every vertex has degree at least k, every cycle contains at least 4 vertices, but which does not contain a path of length 2k.

matrix Ag of G, with respect to the listing of vertices, is an n x n 0-1 matrix with a 1 wherever there is an edge connecting the two vertices better for graphs with large # of vertices can be used to represent graphs with loops and multiple edges, a loop is represented by a 1 at (i,i)...Graph - find vertex reachable from all other vertices. Ask Question 6. 3. Given a graph, how can we determine whether or not there exists a vertex v, from which all other vertices are reachable. the algorithm should be as efficient as possible. I know how to do it if we are checking for a given vertex; we could do dfs on the reverse graph. But for this question, it seems inefficient to do it

The predecessor subgraph G is a breadth-first tree if V consists of the vertices reachable from s and, for all v V, there is a unique simple path from s to v in G that is also a shortest path from s to v in G. twitch how to turn off discord sound Given a subset of vertices U ⊆ V, the subgraph of G induced by U , denoted hUi , is the graph whose vertex set is U , and its edge set contains all edges from G connecting vertices in U ..

- matching covering all vertices of G. Let M be a matching. The vertices that are incident to an edge of M are matched or covered by M. If U is a set of vertices covered by M, then we say that M saturates U. The vertices which are not covered are said to be exposed. Let G=(V,E) be a graph and M a matching. An M-alternating path in G is a path whose edges are alternatively in E\M and in M. An M

- in G that match up all vertices of G (i.e., the edges of a 1-regular spanning subgraph of G.) But since 32 > 30, it is impossible to ﬁnd such a collection of pairwise disjoint edges, as each edge “covers” exactly two vertices, one from each part of the bipartition. A generalization is that the vertices in the two parts of a bipartition of any bipartite graph cannot be matched up using
