+Bipartite Graph
+---------------
+
+A bipartite graph (also called a two-mode graph) is a type of graph where
vertices are separated into two disjoint sets. These sets are usually called
top and bottom vertices. A single edge in this graph can only connect vertices
from opposite sets (i.e. bottom vertex to top vertex) and cannot connect to
vertices in the same set.
+
+Theses graphs have wide application in practice and can be a more natural
choice for particular domains. For example to represent authorship of
scientific papers top vertices can represent scientific papers while bottom
nodes will represent authors. Naturally a node between a top and a bottom nodes
would represent an authorship of a particular scientific paper. Another common
example for applications of bipartite graphs is a relationships between actors
and movies. In this case an edge represents that a particular actor played in a
movie.
