subtree isomorphism problem



Dear all,


I want to ask a problem about subtree ismorphism. Given trees H and G,
find a subtree of G which is isomorphic to H or decide that there is no

such subtree, this is traditional subtree isomorphism problem.


Could anyone advise on this problem, given trees H and G, find all
subtree of G which are isomorphic to H.


Sincerely,
Joe
