We present new fixed parameter algorithms for the FACE COVER problem on plane graphs. We show that if a plane graph has a face cover with at most k faces then its treewidth is bounded by O(驴k). An approximate tree decomposition can be obtained in linear time, and this is used to find an algorithm computing the face cover number in time O(c驴kn) for some constant c. Next we show that the problem is in linear time reducible to a problem kernel of O(k2) vertices, and this kernel can be used to obtain an algorithm that runs in time O(c驴k +n) for some other constant c. For the k-DISJOINT CYCLES PROBLEM AND THE k- FEEDBACK VERTEX SET problem on planar graphs we obtain algorithms that run in time O(c驴k log kn) for some constant c. For the k-FEEDBACK VERTEX SET problem we can further reduce the problem to a problem kernel of size O(k3) and obtain an algorithm that runs in time O(c驴k log k+n) for some constant c1.
