Random knapsack in expected polynomial time
In this paper, we present the first average-case analysis proving an expected polynomial running time for an exact algorithm for the 0/1 knapsack problem. In particular, we prove,...

Pairwise Markov Random Fields and its Application in Textured Images Segmentation
The use of random fields, which allows one to take into account the spatial interaction among random variables in complex systems, is a frequent tool in numerous problems of stati...

Finding cores of random 2-SAT formulae via Poisson cloning
For the random 2-SAT formula F(n, p), let FC(n, p) be the formula left after the pure literal algorithm applied to F(n, p) stops. Using the recently developed Poisson cloning model...

Counting good truth assignments of random k-SAT formulae
We present a deterministic approximation algorithm to compute logarithm of the number of `good' truth assignments for a random k-satisfiability (k-SAT) formula in polynomial ...

Satisfiability Decay along Conjunctions of Pseudo-Random Clauses
Abstract. k-SAT is a fundamental constraint satisfaction problem. It involves S(m), the satisfaction set of the conjunction of m clauses, each clause a disjunction of k literals. T...
