Exact Quantum Algorithms for the Leader Election Problem
Abstract. It is well-known that no classical algorithm can solve exactly (i.e., in bounded time without error) the leader election problem in anonymous networks. This paper propose...

Specifying Truck Movement in Traffic Models Using Cell-DEVS
A specification language was defined to outline sections of cities as cell spaces. The goal is to allow the definition of complex traffic models in a simple fashion for the modele...

Improved Approximate Pattern Matching on Hypertext
The problem of approximate pattern matching on hypertext is de ned and solved by Amir et al. in O(m(nlogm + e)) time, where m is the length of the pattern, n is the total text size...

Smooth Optimization with Approximate Gradient
We show that the optimal complexity of Nesterov's smooth first-order optimization algorithm is preserved when the gradient is only computed up to a small, uniformly bounded er...
