Transitive Reduction


The transitive reduction of a binary relation R on a set X is the minimum relation R^' on X with the same transitive closure as R. Thus aR^'b for any elements a and b of X, provided that aRb and there exists no element c of X such that aRc and cRb.

The transitive reduction of a graph G is the smallest graph R(G) such that C(G)=C(R(G)), where C(G) is the transitive closure of G (Skiena 1990, p. 203).
