Topological structure of solution sets to multi-valued asymptotic problems.
On the parameterized complexity of approximate counting
In this paper we study the parameterized complexity of approximating the parameterized counting problems contained in the class , the parameterized analogue of . We prove a parameterized analogue of a famous theorem of Stockmeyer claiming that approximate counting belongs to the second level of the polynomial hierarchy.
