It is known that the maximum independent set problem is NPcomplete for subcubic graphs, i.e. graphs of vertex degree at most 3. Moreover, the problem is NPcomplete for 3regular Hamiltonian graphs and for Hfree subcubic graphs whenever H contains a connected component which is not a tree with at most 3 leaves. We show that if every connected component of His a tree with at most 3 leaves and at most 7 vertices, then the problem can be solved for Hfree subcubic graphs in polynomial time. We also strengthen the NPcompleteness of the problem on 3regular Hamiltonian graphs by showing that the problem is APXcomplete in this class.
