On search in peer-to-peer file sharing systems
We consider the problem of information retrieval in a peerto-peer file sharing system. We assume that peers are unreliable, metadata are sparse, and queries are short. In light o...

Bifurcation Analysis of Large Equilibrium Systems in Matlab
The Continuation of Invariant Subspaces (CIS) algorithm produces a smoothly varying basis for an invariant subspace R(s) of a parameter-dependent matrix A(s). In the case when A(s)...

Intermediate Consistencies by Delaying Expensive Propagators
What makes a good consistency ? Depending on the constraint, it may be a good pruning power or a low computational cost. By "weakening" arc-consistency, we propose to de...

Precise N-Gram Probabilities from Stochastic Context-Free Grammars
We present an algorithm for computing n-gram probabilities from stochastic context-free grammars, a procedure that can alleviate some of the standard problems associated with n-gr...
