Multicast Trees for Collaborative Applications
—Current implementations of real-time collaborative applications rely on a dedicated infrastructure to carry out all synchronizing and communication functions, and require all en...

Optimal Direct Sum Results for Deterministic and Randomized Decision Tree Complexity
A Direct Sum Theorem holds in a model of computation, when for every problem solving some k input instances together is k times as expensive as solving one. We show that Direct Su...

An (Almost) Constant-Effort Solution-Verification Proof-of-Work Protocol Based on Merkle Trees
Proof-of-work schemes are economic measures to deter denial-of-service attacks: service requesters compute moderately hard functions the results of which are easy to check by the ...

Robust Polynomials and Quantum Algorithms
We define and study the complexity of robust polynomials for Boolean functions and the related fault-tolerant quantum decision trees, where input bits are perturbed by noise. We ...

A Demand Driven Computation Strategy for Lazy Narrowing
Many recent proposals for the integration of functional and logic programming use conditional term rewriting systems (CTRS) as programs and narrowing as goal solving mechanism. Thi...
