Is there a natural (and hopefully well-known) maximization problem that is known to be in FPT? For instance, Vertex Cover is in FPT, but it's a minimization problem. I'm looking for natural maximization problems that are in FPT.
Edit (clarification): "I assume you mean a maximization problem that is in FPT when parameterized by the solution size." This is exactly what I meant to ask, as the first comment (by Jan Johannsen) points out.
