Parameterized Model Checking of Ring-Based Message Passing Systems
The Parameterized Model Checking Problem (PMCP) is to decide whether a temporal property holds for a uniform family of systems,  ¢¡ , comprised of finite, but arbitrarily many,...

Attack-resistant frequency counting
We present collaborative peer-to-peer algorithms for the problem of approximating frequency counts for popular items distributed across the peers of a large-scale network. Our alg...

Resolution Is Not Automatizable Unless W[P] Is Tractable
We show that neither Resolution nor tree-like Resolution is automatizable unless the class W[P] from the hierarchy of parameterized problems is fixed-parameter tractable by randomi...

Parking Functions, Stack-Sortable Permutations, and Spaces of Paths in the Johnson Graph
We prove that the space of possible final configurations for a parking problem is parameterized by the vertices of a regular Bruhat graph associated to a 231-avoiding permutation,...

Learning Convex Combinations of Continuously Parameterized Basic Kernels
We study the problem of learning a kernel which minimizes a regularization error functional such as that used in regularization networks or support vector machines. We consider thi...
