We present a fixed-parameter algorithm that constructively solves the
*k*-dominating set problem on graphs excluding one of the*K*_{5}or*K*_{3,3}as a minor in time*O*(4^{16.5 √k}*n*^{O(1)}), which is an exponential factor faster than the previous*O*(2^{O(k)}n^{O(1)}). In fact, we present our algorithm for any*H*-minor-free graph where*H*is a single-crossing graph (can be drawn in the plane with at most one crossing) and obtain the algorithm for*K*_{3,3}(*K*_{5})-minor-free graphs as a special case. As a consequence, we extend our results to several other problems such as vertex cover, edge dominating set, independent set, clique-transversal set, kernels in digraphs, feedback vertex set and a series of vertex removal problems. Our work generalizes and extends the recent result of exponential speedup in designing fixed-parameter algorithms on planar graphs by Alber et al. to other (non-planar) classes of graphs. **Comments**:- This paper is also available from SpringerLink.
