subgraph-isomorphisms G1 G2 #!optional semantic-feasibility?procedure

Returns a lazy-seq of all match sets between G1 and G2. Each isomorphism in the lazy-seq is represented as a set of pairs which lists the match between G1 and G2. If subgraph-isomorphisms is used instead, the algorithm attempts to find a subgraph in G1 that is isomorphic to G2.

G1
the first graph
G2
the second graph
semantic-feasibility?
a procedure which evaluates semantic feasibility for a candidate pair. See discussion above.
