trc :: DynGraph gr => gr a b -> gr a ()

Finds the reflexive-transitive closure of a directed graph. Given a graph G=(V,E), its reflexive-transitive closure is the graph: G* = (V,E*) where E*={(i,j): i,j in V and either i = j or there is a path from i to j in G}

rc :: DynGraph gr => gr a b -> gr a ()

Finds the reflexive closure of a directed graph. Given a graph G=(V,E), its reflexive closure is the graph: G* = (V,Er union E) where Er = {(i,i): i in V}

tc :: DynGraph gr => gr a b -> gr a ()

Finds the transitive closure of a directed graph. Given a graph G=(V,E), its transitive closure is the graph: G* = (V,E*) where E*={(i,j): i,j in V and there is a path from i to j in G}
