Jan 31, 2025 · The transitive closure of a binary relation R on a set X is the minimal transitive relation R^' on X that contains R. Thus aR^'b for any elements a and b of X provided that there …

It can be shown that the transitive closure of a relation R on A which is a finite set is union of iteration R on itself |A| times. Hence the matrix representation of transitive closure is joining all …

The program calculates transitive closure of a relation represented as an adjacency matrix. Element (i,j) in the matrix is equal to 1 if the pair (i,j) is in the relation. Otherwise, it is equal to 0.

Transitive Closure. The transitive closure of a binary relation \(R\) on a set \(A\) is the smallest transitive relation \(t\left( R \right)\) on \(A\) containing \(R.\) The transitive closure is more …
