Revisiting the non-equilibrium phase transitions of the continuous-trait Axelrod model
Sandro M. Reia, Paulo R. A. Campos, José F. Fontanari
We investigate the non-equilibrium phase transitions of the continuous-trait Axelrod model, an agent-based framework where individual culture is represented by a vector of cont…
SF-LIFE: A Large-Scale Simulated Movement Dataset for the San Francisco Bay Area
Chanuka Algama, Taylor Anderson, Henrique Ferraz de Arruda +14
We introduce SF-LIFE, a large-scale simulated movement dataset designed to accelerate research in transportation, mobility, and machine learning. The dataset contains 3,024,000,000…
Towards Universal Urban Patterns-of-Life Simulation
Sandro M. Reia, Henrique F. de Arruda, Shiyang Ruan +3
Understanding urban mobility requires models that capture how people interact with and navigate the built environment. We present a scalable, generalizable agent-based framework in…
Non-equilibrium phase transition and cultural drift in the continuous-trait Axelrod model
Paulo R. A. Campos, Sandro M. Reia, José F. Fontanari
The standard Axelrod model of cultural dissemination, based on discrete cultural traits, exhibits a non-equilibrium phase transition but is inherently limited by its inability to c…
Extracting the U.S. building types from OpenStreetMap data
Henrique F. de Arruda, Sandro M. Reia, Shiyang Ruan +4
Building type information is crucial for population estimation, traffic planning, urban planning, and emergency response applications. Although essential, such data is often not re…
Function and form of U.S. cities
Sandro M. Reia, Taylor Anderson, Henrique F. Arruda +4
The relationship between urban form and function is a complex challenge that can be examined from multiple perspectives. In this study, we propose a method to characterize the urba…
Cultural heterogeneity constrains diffusion of innovations
Aruane M. Pineda, Sandro M. Reia, Colm Connaughton +2
Rogers' diffusion of innovations theory asserts that cultural similarity among individuals plays a crucial role in the acceptance of an innovation in a community. However, most stu…
Supporting Post-disaster Recovery with Agent-based Modeling in Multilayer Socio-physical Networks
Jiawei Xue, Sangung Park, Washim Uddin Mondal +3
The examination of post-disaster recovery (PDR) in a socio-physical system enables us to elucidate the complex relationships between humans and infrastructures. Although existing s…
Spatial Structure of City Population Growth
Sandro M. Reia, P. Suresh C. Rao, Marc Barthelemy +1
We show here that population growth, resolved at the county level, is spatially heterogeneous both among and within the U.S. metropolitan statistical areas. Our analysis of data fo…
A pattern recognition approach for distinguishing between prose and poetry
Henrique F. de Arruda, Sandro M. Reia, Filipi N. Silva +2
Poetry and prose are written artistic expressions that help us to appreciate the reality we live. Each of these styles has its own set of subjective properties, such as rhyme and r…
Long-term Scientific Impact Revisited
Sandro M. Reia, José F. Fontanari
Citation based measures are widely used as quantitative proxies for subjective factors such as the importance of a paper or even the worth of individual researchers. Here we analyz…
A SIR epidemic model for citation dynamics
Sandro M. Reia, José F. Fontanari
The study of citations in the scientific literature crosses the boundaries between the traditional branches of science and stands on its own as a most profitable research field dub…
Wisdom of crowds: much ado about nothing
Sandro M. Reia, José F. Fontanari
The puzzling idea that the combination of independent estimates of the magnitude of a quantity results in a very accurate prediction, which is superior to any or, at least, to most…
The surprising little effectiveness of cooperative algorithms in parallel problem solving
Sandro M. Reia, Larissa F. Aquino, José F. Fontanari
Biological and cultural inspired optimization algorithms are nowadays part of the basic toolkit of a great many research domains. By mimicking processes in nature and animal societ…
Comfort-driven mobility produces spatial fragmentation in Axelrod's model
Sandro M. Reia, Paulo F. Gomes, José F. Fontanari
Axelrod's model for the dissemination of culture combines two key ingredients of social dynamics: social influence, through which people become more similar when they interact, and…
Policies for allocation of information in task-oriented groups: elitism and egalitarianism outperform welfarism
Sandro M. Reia, Paulo F. Gomes, José F. Fontanari
Communication or influence networks are probably the most controllable of all factors that are known to impact on the problem-solving capability of task-forces. In the case connect…
Individual decision making in task-oriented groups
Sandro M. Reia, Paulo F. Gomes, José F. Fontanari
The strategies adopted by individuals to select relevant information to pass on are central to understanding problem solving by groups. Here we use agent-based simulations to revis…
Agent-based models of collective intelligence
Sandro M. Reia, André C. Amado, José F. Fontanari
Collective or group intelligence is manifested in the fact that a team of cooperating agents can solve problems more efficiently than when those agents work in isolation. Although…
Mobility helps problem-solving systems to avoid Groupthink
Paulo F. Gomes, Sandro M. Reia, Francisco A. Rodrigues +1
Groupthink occurs when everyone in a group starts thinking alike, as when people put unlimited faith in a leader. Avoiding this phenomenon is a ubiquitous challenge to problem-solv…
Impact of centrality on cooperative processes
Sandro M. Reia, Sebastian Herrmann, José F. Fontanari
The solution of today's complex problems requires the grouping of task forces whose members are usually connected remotely over long physical distances and different time zones. He…
Effect of long-range interactions on the phase transition of Axelrod's model
Sandro M. Reia, José F. Fontanari
Axelrod's model with cultural features, where each feature can assume states drawn from a Poisson distribution of parameter , exhibits a continuous nonequilibrium phas…
Effect of group organization on the performance of cooperative processes
Sandro M. Reia, José F. Fontanari
Problem-solving competence at group level is influenced by the structure of the social networks and so it may shed light on the organization patterns of gregarious animals. Here we…
Nonsynchronous updating in the multiverse of cellular automata
Sandro M. Reia, Osame Kinouchi
In this paper we study updating effects on cellular automata rule space. We consider a subset of 6144 order-3 automata from the space of 262144 bi-dimensional outer-totalistic rule…
Conway's game of life is a near-critical metastable state in the multiverse of cellular automata
Sandro Martinelli Reia, Osame Kinouchi
Conway's cellular automaton Game of LIFE has been conjectured to be a critical (or quasicritical) dynamical system. This criticality is generally seen as a continuous order-disorde…
