Diffusion of innovations in Axelrod's model
Paulo F. C. Tilles, José F. Fontanari
Axelrod's model for the dissemination of culture contains two key factors required to model the process of diffusion of innovations, namely, social influence (i.e., individuals bec…
The consensus in the two-feature two-state one-dimensional Axelrod model revisited
Elias J. P. Biral, Paulo F. C. Tilles, José F. Fontanari
The Axelrod model for the dissemination of culture exhibits a rich spatial distribution of cultural domains, which depends on the values of the two model parameters: , the numbe…
Reinforcement and inference in cross-situational word learning
Paulo F. C. Tilles, Jose F. Fontanari
Cross-situational word learning is based on the notion that a learner can determine the referent of a word by finding something in common across many observed uses of that word. He…
Critical behavior in a cross-situational lexicon learning scenario
P. F. C. Tilles, J. F. Fontanari
The associationist account for early word-learning is based on the co-occurrence between objects and words. Here we examine the performance of a simple associative learning algorit…
Minimal model of associative learning for cross-situational lexicon acquisition
Paulo F. C. Tilles, Jose F. Fontanari
An explanation for the acquisition of word-object mappings is the associative learning in a cross-situational scenario. Here we present analytical results of the performance of a s…
Mean-field analysis of the majority-vote model broken-ergodicity steady state
Paulo F. C. Tilles, Jose F. Fontanari
We study analytically a variant of the one-dimensional majority-vote model in which the individual retains its opinion in case there is a tie among the neighbors' opinions. The ind…
Local attractors, degeneracy and analyticity: symmetry effects on the locally coupled Kuramoto model
Paulo F. C. Tilles, Hilda A. Cerdeira, Fernando F. Ferreira
In this work we study the local coupled Kuramoto model with periodic boundary conditions. Our main objective is to show how analytical solutions may be obtained from symmetry assum…
Multistable behavior above synchronization in a locally coupled Kuramoto model
Paulo F. C. Tilles, Fernando F. Ferreira, Hilda A. Cerdeira
A system of nearest neighbors Kuramoto-like coupled oscillators placed in a ring is studied above the critical synchronization transition. We find a richness of solutions when the…
A Markovian Model Market - Akerlof's Lemmons and the Asymmetry of Information
Paulo F. C. Tilles, Fernando F. Ferreira, Gerson Francisco +2
In this work we study an economic agent based model under different asymmetric information degrees. This model is quite simple and can be treated analytically since the buyers eval…
