We present a new class of methods for the global optimization of continuous variables based on simulated annealing (SA). The coupled SA (CSA) class is characterized by a set of parallel SA processes… (More)

In this paper we describe the use of coupling to interconnect different Simulated Annealing (SA) processes. The objective is to allow cooperative behavior among the processes in order to improve… (More)

We introduce a spherical Hopfield-type neural network involving neurons and patterns that are continuous variables. We study both the thermodynam-ics and dynamics of this model. In order to have a… (More)

Using the replica-symmetric mean-field theory approach the thermodynamic and retrieval properties of extremely diluted symmetric Q-Ising neural networks are studied. In particular, capacity-gain… (More)

Artificial neural networks have been widely applied to memorize and retrieve information. During the last number of years there has been considerable interest in neural networks with multistate… (More)

The signal-to-noise analysis of the Little-Hopfield model revisited Abstract Using the generating functional analysis an exact recursion relation is derived for the time evolution of the effective… (More)

Using a probabilistic approach we study the parallel dynamics of fully connected Q-Ising neural networks for arbitrary Q. A Lya-punov function is shown to exist at zero temperature. A recursive… (More)

We study the thermodynamic properties of spin systems on small-world hypergraphs, obtained by superimposing sparse Poisson random graphs with p -spin interactions onto a one-dimensional Ising chain… (More)

We study the thermodynamic properties of spin systems with bond-disorder on small-world hypergraphs, obtained by superimposing a one-dimensional Ising chain onto a random Bethe graph with p-spin… (More)

We study the behavior of the inverse participation ratio and the localization transition in infinitely large random matrices through the cavity method. Results are shown for two ensembles of random… (More)
