Lower bounds for context-free grammars
Ellul, Krawetz, Shallit and Wang prove an exponential lower bound on the size of any context-free grammar generating the language of all permutations over some alphabet. We genera...

Fast leader election in anonymous rings with bounded expected delay
We propose a probabilistic network model, called asynchronous bounded expected delay (ABE), which requires a known bound on the expected message delay. In ABE networks all asynchr...

Restricted compositions and permutations: From old to new Gray codes
Any Gray code for a set of combinatorial objects defines a total order relation on this set: x is less than y if and only if y occurs after x in the Gray code list. Let ≺ denot...

On the cryptanalysis of the hash function Fugue: Partitioning and inside-out distinguishers
Fugue is an intriguing hash function design with a novel shift-register based compression structure and has formal security proofs e.g. against collision attacks. In this paper, w...

Edge-colored graphs with applications to homogeneous faults
In this paper, we use the concept of edge-colored graphs to model homogeneous faults in networks. We then use this model to study the minimum connectivity (and design) requirement...

The regularized least squares algorithm and the problem of learning halfspaces
We provide sample complexity of the problem of learning halfspaces with monotonic noise, using the regularized least squares algorithm in the reproducing kernel Hilbert spaces (RKH...

A note on improving the performance of approximation algorithms for radiation therapy
The segment minimization problem consists of representing an integer matrix as the sum of the fewest number of integer matrices each of which have the property that the non-zeroes...

Improved approximation algorithms for minimum AND-circuits problem via k-set cover
Arpe and Manthey [Algorithmica’09] recently studied the minimum ANDcircuit problem, which is a circuit minimization problem, and showed some results including approximation algo...
