In this paper we consider two above lower bound parameterizations of the NodeMultiway Cut problem -- above the maximum separating cut and above a natural LP-relaxation -- and prove them to be fixed-parameter tractable. Our results imply O*(4k) algorithms for Vertex Coverabove Maximum Matching and Almost 2-SAT as well as an O*(2k) algorithm for NodeMultiway Cut with a standard parameterization by the solution size, improving previous bounds for these problems.
