DiGraphMatcher.syntactic_feasibility

DiGraphMatcher.syntactic_feasibility(G1_node, G2_node)

Returns True if adding (G1_node, G2_node) is syntactically feasible.

This function returns True if it is adding the candidate pair to the current partial isomorphism/monomorphism mapping is allowable. The addition is allowable if the inclusion of the candidate pair does not make it impossible for an isomorphism/monomorphism to be found.
