It is known to be NP-hard to decide whether a graph can be made chordal by the deletion of k vertices. Here we present a uniformly polynomial-time algorithm for the problem: the running time is f(k) · nα for some constant α not depending on k and some f depending only on k. For large values of n, such an algorithm is much better than trying all the O(nk) possibilities. Therefore, the chordal deletion problem parameterized by the number k of vertices to be deleted is fixed-parameter tractable. This answers an open question of Cai [2]. © Springer-Verlag Berlin Heidelberg 2006.
