Ordered Binary Decision Diagrams, Pigeonhole Formulas and Beyond
Groote and Zantema proved that a particular OBDD computation of the pigeonhole formula has exponential size, and that limited OBDD derivations cannot simulate resolution polynomia...

Bounds on the cleaning times of robot vacuums
We show a robot vacuum using a protocol that next cleans the "dirtiest" incident edge may take exponential time to clean a network. This disproves a conjecture of Messing...

On the Relative Complexity of Resolution Refinements and Cutting Planes Proof Systems
An exponential lower bound for the size of tree-like cutting planes refutations of a certain family of conjunctive normal form (CNF) formulas with polynomial size resolution refuta...

Analysis of Exponential Backoff with Multipacket Reception in Wireless Networks
A collision resolution scheme is essential to the performance of a random-access wireless network. Most schemes employ exponential backoff (EB) to adjust the transmission attempt ...

Parameter estimation for exponential sums by approximate Prony method
The recovery of signal parameters from noisy sampled data is a fundamental problem in digital signal processing. In this paper, we consider the following spectral analysis problem...
