Evolving division of labor in a response threshold model
José F. Fontanari, Viviane M. de Oliveira, Paulo R. A. Campos
The response threshold model explains the emergence of division of labor (i.e., task specialization) in an unstructured population by assuming that the individuals have different p…
Model inspired by population genetics to study fragmentation of brittle plates
M. A. F. Gomes, Viviane M. de Oliveira
We use a model whose rules were inspired by population genetics, the random capability growth model, to describe the statistical details observed in experiments of fragmentation of…
Complementarity and diversity in a soluble model ecosystem
Viviane M. de Oliveira, J. F. Fontanari
Complementarity among species with different traits is one of the basic processes affecting biodiversity, defined as the number of species in the ecosystem. We present here a solub…
Extinctions in the random replicator model
Viviane M. de Oliveira, J. F. Fontanari
The statistical properties of an ecosystem composed of species interacting via pairwise, random interactions and deterministic, concentration limiting self-interaction are studied…
Random replicators with high-order interactions
Viviane M. de Oliveira, J. F. Fontanari
We use tools of the equilibrium statistical mechanics of disordered systems to study analytically the statistical properties of an ecosystem composed of N species interacting via r…
Metastable States in High Order Short-Range Spin Glasses
Viviane M. de Oliveira, J. F. Fontanari, Peter F. Stadler
The mean number <N> of metastable states in higher order short-range spin glasses is estimated analytically using a variational method introduced by Tanaka and Edwards for very lar…
Replica analysis of the p-spin interactions Ising spin-glass model
Viviane M de Oliveira, J F Fontanari
The thermodynamics of the infinite-range Ising spin glass with p-spin interactions in the presence of an external magnetic field h is investigated analytically using the replica me…
Landscape statistics of the p-spin Ising model
Viviane M de Oliveira, J F Fontanari
The statistical properties of the local optima (metastable states) of the infinite range Ising spin glass with p-spin interactions in the presence of an external magnetic field h a…
