Cumulative suspicion and absorption dynamics in an agent-based Mafia game
Eduardo Velasco Stock, Roberto da Silva
The Mafia game, also known as Werewolf, describes a competition between a coordinated minority whose identities are concealed and a larger good faction composed primarily of uninfo…
Patterns in a Warming Ocean: Stylized Spectral Facts on Sea Surface Temperature
Roberto da Silvaa, Eliseu Venites Filho, Eduardo V. Stock +1
Capturing stylized facts and their evolution is essential for understanding the impact of climate change on complex environmental systems. In this work, we investigate the spectral…
The number of spanning trees as an indicator of critical phenomena: When Kirchhoff meets Ising
Roberto da Silva, Henrique A. Fernandes, Paulo G. Freitas +3
Visibility graphs are spatial interpretations of time series. When derived from the time evolution of physical systems, the graphs associated with such series may exhibit propertie…
Mean-field and Monte Carlo Analysis of Multi-Species Dynamics of agents
Eduardo Velasco Stock, Roberto da Silva, Sebastian Gonçalves
We propose a mean-field (MF) approximation for the recurrence relation governing the dynamics of species of particles on a square lattice, and we simultaneously perform Monte C…
