An Isomorphism between Subexponential and Parameterized Complexity Theory
We establish a close connection between (sub)exponential time complexity and parameterized complexity by proving that the so-called miniaturization mapping is a reduction preservi...

A Duality between Clause Width and Clause Density for SAT
We consider the relationship between the complexities of - and those of restricted to formulas of constant density. Let be the infimum of those such that - on variables can be dec...

Optimal Hardness Results for Maximizing Agreements with Monomials
We consider the problem of finding a monomial (or a term) that maximizes the agreement rate with a given set of examples over the Boolean hypercube. The problem is motivated by le...

Test Generation Based on Symbolic Specifications
Abstract. Classical state-oriented testing approaches are based on simple machine models such as Labelled Transition Systems (LTSs), in which data is represented by concrete values...

Making Hard Problems Harder
We consider a general approach to the hoary problem of (im)proving circuit lower bounds. We define notions of hardness condensing and hardness extraction, in analogy to the corres...
