title = "Smaller kernels for hitting set problems of constant arity",
abstract = "We demonstrate a kernel of size O(k2) for 3-HITTING SET (HITTING SET when all subsets in the collection to be hit are of size at most three), giving a partial answer to an open question of Niedermeier by improving on the O(k3) kernel of Niedermeier and Rossmanith. Our technique uses the Nemhauser-Trotter linear-size kernel for VERTEX COVER, and generalizes to demonstrating a kernel of size O(kr-1) for r-HITTING SET (for fixed r).",
