We study the complexity of various fundamental counting problems that arise in the context of incomplete databases, i.e., relational databases that can contain unknown values in the form of labeled nulls. Specifically, we assume that the domains of ...
We develop a parameterized complexity theory for counting problems. As the basis of this theory, we introduce a hierarchy of parameterized counting complexity classes #W$[t]$, for $t\ge 1$, that corresponds to Downey and Fellows's W-hierarchy [R. G. ...
Hard counting problems with easy decision version, like computing the permanent and counting independent sets, are of particular importance in counting complexity theory. TotP is the class of all self-reducible problems in # P with ...
