An undirected graph is called Biconnected if there are two vertex-disjoint paths between any two vertices. In a Biconnected Graph, there is a simple cycle… Read More

An edge in an undirected connected graph is a bridge iff removing it disconnects the graph. For a disconnected undirected graph, definition is similar, a… Read More

A vertex in an undirected connected graph is an articulation point (or cut vertex) if removing it (and edges through it) disconnects the graph. Articulation… Read More

A directed graph is strongly connected if there is a path between all pairs of vertices. A strongly connected component (SCC) of a directed graph… Read More

Given a Weighted Directed Acyclic Graph and a source vertex in the graph, find the shortest paths from given source to all other vertices. Recommended:… Read More

Topological sorting for Directed Acyclic Graph (DAG) is a linear ordering of vertices such that for every directed edge u v, vertex u comes… Read More

A Bipartite Graph is a graph whose vertices can be divided into two independent sets, U and V such that every edge (u, v) either… Read More

Given a directed graph, find out if a vertex j is reachable from another vertex i for all vertex pairs (i, j) in the given… Read More

Given a graph and a source vertex src in graph, find shortest paths from src to all vertices in the given graph. The graph may… Read More

We have discussed Kruskal’s algorithm for Minimum Spanning Tree. Like Kruskal’s algorithm, Prim’s algorithm is also a Greedy algorithm. It starts with an empty spanning tree.… Read More

A graph is a data structure that consists of the following two components: 1. A finite set of vertices also called as nodes. 2. A finite set… Read More
