bipartite structure
Definitions
A structure whose elements are divided into two distinct sets, with relationships occurring only between elements of different sets.
In graph theory, a graph whose vertices can be partitioned into two sets so that every edge connects a vertex in one set to a vertex in the other.
Examples
The graph has a bipartite structure, with students on one side and courses on the other.
Researchers used the bipartite structure to map connections between authors and papers.
