Correlation Inequalities for Spin Glass in one Dimension
Pierluigi Contucci, Francesco Unguendoli
We prove two inequalities for the direct and truncated correlation for the nearest-neighboor one-dimensional Edwards-Anderson model with symmetric quenched disorder. The second ine…

Interpolating Greedy and Reluctant Algorithms
P. Contucci, C. Giardina', C. Giberti +2
In a standard NP-complete optimization problem we introduce an interpolating algorithm between the quick decrease along the gradient (greedy dynamics) and a slow decrease close to…
