A Probabilistic Approach to Problems Parameterized Above Tight Lower Bound
Gregory Gutin, Eun Jung Kim, Stefan Szeider, Anders Yeo · 2009
We introduce a new approach for establishing fixed-parameter tractability of problems parameterized above tight lower bounds. To illustrate the approach we consider three problems of this type of unknown complexity that were introduced by Mahajan, Raman and Sikdar (J. Comput. Syst. Sci. 75, 2009). We show that a generalization of one of the problems and non-trivial special cases of the other two are fixed-parameter tractable.
