On some features of Quadratic Unconstrained Binary Optimization with random coefficients
Marco Isopi, Benedetto Scoppola, Alessio Troiani
Quadratic Unconstrained Binary Optimization (QUBO or UBQP) is concerned with maximizing/minimizing the quadratic form with a matrix…
Multitasking network with fast noise
Elena Agliari, Adriano Barra, Andrea Galluzzi +1
We consider the multitasking associative network in the low-storage limit and we study its phase diagram with respect to the noise level and the degree of dilution in patte…
On the "Matrix Approach" to interacting particle systems
Luca De Sanctis, Marco Isopi
Derrida et al. and Schütz and Stinchcombe gave algebraic formulas for the correlation functions of the partially asymmetric simple exclusion process. Here we give a fairly general…
Coarsening, Nucleation, and the Marked Brownian Web
L. R. G. Fontes, M. Isopi, C. M. Newman +1
Coarsening on a one-dimensional lattice is described by the voter model or equivalently by coalescing (or annihilating) random walks representing the evolving boundaries between re…
The Brownian web: Characterization and convergence
L. R. G. Fontes, M. Isopi, C. M. Newman +1
The Brownian web (BW) is the random network formally consisting of the paths of coalescing one-dimensional Brownian motions starting from every space-time point in R\timesR. We ext…
On the Location of the 1-particle Branch of the Spectrum of the Disordered Stochastic Ising Model
M. Gianfelice, M. Isopi
We analyse the lower non trivial part of the spectrum of the generator of the Glauber dynamics, which we consider a positive operator, for a d-dimensional nearest neighbour Ising m…
