The graph isomorphism problem is in NP, but has been neither proven NP-complete nor found to be solved by a polynomial-time algorithm (Garey and Johnson, 1979, Chapter 7). Subgraph isomorphism checking is the analogue of graph isomorphism checking in a setting in which the two graphs have different sizes.
