Graph reversal algorithm

The problem of graph exploration can be seen as a variant of graph traversal. It is an online problem, meaning that the information about the graph is only revealed during the runtime of the algorithm. A common model is as follows: given a connected graph G = (V, E) with non-negative edge weights. The algorithm starts at some vertex, and knows all incident outgoing edges and the vertices at the end of these edges—but not more. When a new vertex is visited, then again all in… WebMar 24, 2024 · DFS. 1. Overview. In graph theory, one of the main traversal algorithms is DFS (Depth First Search). In this tutorial, we’ll introduce this algorithm and focus on implementing it in both the recursive and non-recursive ways. First of all, we’ll explain how does the DFS algorithm work and see how does the recursive version look like.

WebTopological sorting. In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edges may represent ... WebThe problem of graph exploration can be seen as a variant of graph traversal.
