In a joint work with M. Yampolsky, we gave a classification of Thurston maps with parabolic orbifolds based on our previous results on characterization of canonical Thurston obstructions. The obtained results yield a  solution to the problem of algorithmically checking combinatorial equivalence of two Thurston maps.
