On Computation and Communication with Small Bias
We present two results for computational models that allow error probabilities close to 1/2. First, most computational complexity classes have an analogous class in communication ...

Communication Problems in Random Line-of-Sight Ad-Hoc Radio Networks
The line-of-sight networks is a network model introduced recently by Frieze et al. (SODA’07). It considers scenarios of wireless networks in which the underlying environment has...

Approximate Discovery of Random Graphs
In the layered-graph query model of network discovery, a query at a node v of an undirected graph G discovers all edges and non-edges whose endpoints have different distance from ...

Probabilistic Techniques in Algorithmic Game Theory
We consider applications of probabilistic techniques in the framework of algorithmic game theory. We focus on three distinct case studies: (i) The exploitation of the probabilistic...

A VNS Algorithm for Noisy Problems and Its Application to Project Portfolio Analysis
Abstract. Motivated by an application in project portfolio analysis under uncertainty, we develop an algorithm S-VNS for solving stochastic combinatorial optimization (SCO) problem...

An Exponential Gap Between LasVegas and Deterministic Sweeping Finite Automata
A two-way finite automaton is sweeping if its input head can change direction only on the end-markers. For each n ≥ 2, we exhibit a problem that can be solved by a O(n2 )-state ...
