Bipartite graphs

A bipartite graph is a type of network made up of two distinct sets of objects, where connections (edges) only exist between objects from different sets, not within the same set. Imagine two groups—like job seekers and job openings—with lines showing which person is applying for which job. The key feature is that the relationships only run between these groups, not inside them. Bipartite graphs are useful for modeling and analyzing relationships such as matching buyers and sellers, students and courses, or tasks and resources.
