WebAn undirected graph is connected if there is a path between every pair of vertices. A directed graph is strongly connected if there is a path between every pair of vertices. A directed graph is weakly connected if the underlying undirected graph is connected. A connected component of a subgraph H H of a graph G G is maximal connected subgraph. WebA forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees. A polytree (or directed tree or oriented tree or singly connected network) is a directed acyclic graph (DAG) whose underlying undirected graph is a tree. A ...

WebThe algorithm creates a tree of shortest paths from the starting vertex, the source, to all other points in the graph. Dijkstra’s algorithm, published in 1959 and named after its creator Dutch computer scientist Edsger Dijkstra, can be applied on a weighted graph. The graph can either be directed or undirected. Web1. you cannot go to source again from any other edge i.e you can never travel from any other edge towards source edge. 2. if there are two edge A & B with B !=destination_edge with an undirected edge connecting them i.e A-----B then a. if we travelled through A to B then a1. we cannot travel from B to A using same edge.

In graph theory, a path in a graph is a finite or infinite sequence of edges which joins a sequence of vertices which, by most definitions, are all distinct (and since the vertices are distinct, so are the edges). A directed path (sometimes called dipath ) in a directed graph is a finite or infinite sequence of edges which … See more Walk, trail, and path • A walk is a finite or infinite sequence of edges which joins a sequence of vertices.
