On the Complexity of Optimal K-Anonymity
The technique of k-anonymization has been proposed in the literature as an alternative way to release public information, while ensuring both data privacy and data integrity. We p...

Approximating Fractional Multicommodity Flow Independent of the Number of Commodities
Abstract. We describe fully polynomial time approximation schemes for various multicommodity flow problems in graphs with m edges and n vertices. We present the first approximation...

Stochastic Limit-Average Games are in EXPTIME
The value of a finite-state two-player zero-sum stochastic game with limit-average payoff can be approximated to within in time exponential in a polynomial in the size of the gam...

On the fixed-parameter tractability of the equivalence test of monotone normal forms
We consider the problem Monet—given two monotone formulas ϕ in DNF and ψ in CNF, decide whether they are equivalent. While Monet is probably not coNPhard, it is a long standin...
