A taxonomy for denial of service attacks in content-based publish/subscribe systems
Denial of Service (DoS) attacks continue to affect the availability of critical systems on the Internet. The existing DoS problem is enough to merit significant research dedicated...

Learning Unary Automata
We determine the complexity of learning problems for unary regular languages. We begin by investigating the minimum consistent dfa (resp. nfa) problem which is known not to be app...

If NP Languages are Hard on the Worst-Case Then It is Easy to Find Their Hard Instances
We prove that if NP ⊆ BPP, i.e., if SAT is worst-case hard, then for every probabilistic polynomial-time algorithm trying to decide SAT, there exists some polynomially samplable ...

Static analysis for dynamic coupling measures
Coupling measures have important applications in software development and maintenance. They are used to reason about the structural complexity of software and have been shown to p...
