Abstract
In this paper, we first show that the complexity of parameterized m-set packing (resp. m-d matching) counting is \(\sharp \)W[1]-hard by a reduction from parameterized graph (resp. bipartite graph) matching counting \((m\ge 3)\). Subsequently, based on the algorithm for 3-d matching counting, we develop fixed-parameter tractable randomized approximation schemes (FPTRAS) for m-set packing counting, m-d matching counting, and bipartite graph matching counting, respectively. Our results indicate that parameterized m-set packing counting and m-d matching counting are typical examples that are \(\sharp \)W[1]-hard but admit FPTRAS. Furthermore, we show that edge disjoint subgraph packing counting, i.e., a special subgraph counting problem parameterized by the size of the packing, admits FPTRAS even if some of the counted subgraphs don’t have bounded treewidth.
