bipartite graph algorithm dfs

What problems can be formed as bipartite matching?
There are many real world problems that can be formed as Bipartite Matching. For example, consider the following problem: “ There are M job applicants and N jobs. Each applicant has a subset of jobs that he/she is interested in. Each job opening can only accept one applicant and a job applicant can be appointed for only one job.
How to check for bipartiteness of a graph using DFS?
In this post, an approach using DFS has been implemented. Given below is the algorithm to check for bipartiteness of a graph. Use a color array which stores 0 or 1 for every node which denotes opposite colors. Call the function DFS from any node.
How to check if a graph is bipartite?
Given below is the algorithm to check for bipartiteness of a graph. Use a color array which stores 0 or 1 for every node which denotes opposite colors. Call the function DFS from any node. If the node u has not been visited previously, then assign !color [v] to color [u] and call DFS again to visit nodes connected to u.
How does an algorithm determine if a node is bipartite?
While your algorithm is visiting a node v v, if it detects a back edge (v, u) ( v, u) then it backtracks until it reaches u u, using the parent information stored in pi, counts the number of edges, and then decides if it is bipartite or not.
