Check whether a graph is bipartite
A bipartite graph is a graph whose vertices can be divided into two disjoint sets so that every edge connects two vertices from different sets […]
Finding a negative cycle in the graph
You are given a directed weighted graph $G$ with $N$ vertices and $M$ edges. Find any cycle of negative weight in it, if such a […]
Checking a graph for acyclicity and finding a cycle in $O(M)$
Consider a directed or undirected graph without loops and multiple edges. We have to check whether it is acyclic, and if it is not, then […]
Finding articulation points in a graph in $O(N+M)$
We are given an undirected graph. An articulation point (or cut vertex) is defined as a vertex which, when removed along with associated edges, makes […]
Finding bridges in a graph in $O(N+M)$
We are given an undirected graph. A bridge is defined as an edge which, when removed, makes the graph disconnected (or more precisely, increases the […]
Search for connected components in a graph
Given an undirected graph $G$ with $n$ nodes and $m$ edges. We are required to find in it all the connected components, i.e, several groups […]
