Statistical Properties of the Rooted-Tree Encoding of
Pierluigi Contucci, Claudio Giberti, Godwin Osabutey +1
We prime-encode the natural numbers via recursive factorisation, iterated to the exponents, generating a corpus of planar rooted trees equivalently represented as Dyck words. This…
Uphill in reaction-diffusion multi-species interacting particles systems
Francesco Casini, Cristian Giardina, Cecilia Vernia
We study reaction-diffusion processes with multi-species of particles and hard-core interaction. We add boundary driving to the system by means of external reservoirs which inject…
Finite-size corrections for the attractive mean-field monomer-dimer model
Diego Alberici, Pierluigi Contucci, Rachele Luzi +1
The finite volume correction for a mean-field monomer-dimer system with an attractive interaction are computed for the pressure density, the monomer density and the susceptibility.…
Inverse problem robustness for multi-species mean field spin models
M. Fedele, C. Vernia, P. Contucci
The inverse problem method is tested for a class of mean field statistical mechanics models representing a mixture of particles of different species. The robustness of the inversio…
Finding Minima in Complex Landscapes: Annealed, Greedy and Reluctant Algorithms
Pierluigi Contucci, Cristian Giardina', Claudio Giberti +1
We consider optimization problems for complex systems in which the cost function has a multivalleyed landscape. We introduce a new class of dynamical algorithms which, using a suit…
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…
