Competition between evidence-based and alternative medical paradigms in non-infectious diseases
Hermes Benito-Andrés, Alfonso de Miguel-Arribas, Carlos Gracia-Lázaro
Standard epidemiological models coupled with evolutionary game theory (e.g., vaccination games) typically rely on the free-rider dilemma inherent to infectious diseases. In this pa…
Collective cooperation without individual fidelity in LLM agents
Henrique Ferraz de Arruda, Carlos Gracia Lázaro, Alberto Aleta +1
Large language models (LLMs) are increasingly used as agents in simulations of social systems, yet it remains unclear when their behavior can be interpreted as a faithful proxy for…
Contest Dynamics Between Cooperation and Exploitation
Alfonso de Miguel-Arribas, Chengbin Sun, Carlos Gracia-Lázaro +1
Cooperation and competition are fundamental forces shaping both natural and human systems, yet their interplay remains poorly understood. The Prisoner's Dilemma Game (PDG) has long…
Cooperation in costly-access environments
Hugo Perez-Martinez, Carlos Gracia-Lazaro, Fabio Dercole +1
Understanding cooperative behavior in biological and social systems constitutes a scientific challenge, being the object of intense research over the past decades. Many mechanisms…
Polarization inhibits the phase transition of Axelrod's model
Carlos Gracia-Lázaro, Edgardo Brigatti, Alexis R. Hernández +1
We study the effect of polarization in Axelrod's model of cultural dissemination. This is done through the introduction of a cultural feature that takes only two values, while the…
Dynamics of heuristics selection for cooperative behaviour
Felipe Maciel Cardoso, Carlos Gracia-Lazaro, Yamir Moreno
Situations involving cooperative behaviour are widespread among animals and humans alike. Game theory and evolutionary dynamics have provided the theoretical and computational grou…
Effect of memory, intolerance and second-order reputation on cooperation
Chengyi Xia, Carlos Gracia-Lázaro, Yamir Moreno
The understanding of cooperative behavior in social systems has been the subject of intense research over the past decades. In this regard, the theoretical models used to explain c…
Replicator population dynamics of group (-agent) interactions. Broken symmetry, thresholds for metastability and macroscopic behavior
Emmanuel Artiges, Carlos Gracia-Lazaro, Luis Mario Floria +1
We analyze from basic physical considerations the Darwinian competition for reproduction (evolutionary dynamics) of strategists in a Public Goods Game, the archetype for -agent…
Trading in Complex Networks
Felipe M. Cardoso, Carlos Gracia-Lazaro, Frederic Moisan +3
Global supply networks in agriculture, manufacturing, and services are a defining feature of the modern world. The efficiency and the distribution of surpluses across different par…
Analysis of a networked social algorithm for collective selection of a committee of representatives
Alexis R. Hernandez, Carlos Gracia-Lazaro, Edgardo Brigatti +1
A recent work by Hernández et al. introduced a networked voting rule supported by a trust-based social network, where indications of possible representatives were based on individu…
Reputation is required for cooperation to emerge in dynamic networks
Jose A. Cuesta, Carlos Gracia-Lázaro, Yamir Moreno +1
Melamed, Harrell, and Simpson have recently reported on an experiment which appears to show that cooperation can arise in a dynamic network without reputational knowledge, i.e., pu…
A networked voting rule for democratic representation
Alexis R. Hernandez, Carlos Gracia-Lazaro, Edgardo Brigatti +1
We introduce a general framework for exploring the problem of selecting a committee of representatives with the aim of studying a networked voting rule based on a decentralized lar…
Resource heterogeneity leads to unjust effort distribution in climate change mitigation
Julian Vicens, Nereida Bueno-Guerra, Mario Gutiérrez-Roig +6
Fighting against climate change is a global challenge shared by nations with heterogeneous economical resources and individuals with diverse propensity for cooperation. However, we…
Robustness of cultural communities in an open-ended Axelrod's model
Alexis R. Hernandez, Carlos Gracia-Lazaro, Edgardo Brigatti +1
We consider an open-ended set of cultural features in the Axelrod's model of cultural dissemination. By replacing the features in which a high degree of consensus is achieved by ne…
The joint influence of competition and mutualism on the biodiversity of mutualistic ecosystems
Carlos Gracia-Lázaro, Laura Hernández, Javier Borge-Holthoefer +1
Relations among species in ecosystems can be represented by complex networks where both negative (competition) and positive (mutualism) interactions are concurrently present. Recen…
Evolutionary dynamics of N-person Hawk-Dove games
Wei Chen, Carlos Gracia-Lazaro, Zhiwu Li +2
In the animal world, the competition between individuals belonging to different species for a resource often requires the cooperation of several individuals in groups. This paper p…
Cognitive hierarchy theory and two-person games
Carlos Gracia-Lázaro, Luis M. Floría, Yamir Moreno
The outcome of many social and economic interactions, such as stock-market transactions, is strongly determined by the predictions that agents make about the behavior of other indi…
Humans display a reduced set of consistent behavioral phenotypes in dyadic games
Julia Poncela-Casasnovas, Mario Gutierrez-Roig, Carlos Gracia-Lazaro +6
Socially relevant situations that involve strategic interactions are widespread among animals and humans alike. To study these situations, theoretical and experimental works have a…
Emergence of consensus as a modular-to-nested transition in communication dynamics
Javier Borge-Holthoefer, Raquel A. Baños, Carlos Gracia-Lázaro +1
Online social networks have transformed the way in which humans communicate and interact, leading to a new information ecosystem where people send and receive information through m…
Inter-groups information exchange drives Cooperation in the Public Goods Game
Carlos Gracia-Lazaro, Jesus Gomez-Gardenes, Luis Mario Floria +1
In this manuscript we explore the onset of cooperative traits in the Public Goods game. This well-known game involves N-agent interactions and thus reproduces a large number of soc…
Cooperation in changing environments: Irreversibility in the transition to cooperation in networks
C. Gracia-Lázaro, L. M. Floría, J. Gómez-Gardeñes +1
In the framework of the evolutionary dynamics of the Prisoner's Dilemma game on complex networks, we investigate the possibility that the average level of cooperation shows hystere…
Human behavior in Prisoner's Dilemma experiments suppresses network reciprocity
Carlos Gracia-Lazaro, Jose A. Cuesta, Angel Sanchez +1
During the last few years, much research has been devoted to strategic interactions on complex networks. In this context, the Prisoner's Dilemma has become a paradigmatic model, an…
Co-evolutionnary network approach to cultural dynamics controlled by intolerance
Carlos Gracia-Lázaro, Fernando Quijandría, Laura Hernández +2
Starting from Axelrod's model of cultural dissemination, we introduce a rewiring probability, enabling agents to cut the links with their unfriendly neighbors if their cultural sim…
Residential segregation and cultural dissemination: An Axelrod-Schelling model
C. Gracia-Lazaro, L. F. Lafuerza, L. M. Floria +1
In the Axelrod's model of cultural dissemination, we consider mobility of cultural agents through the introduction of a density of empty sites and the possibility that agents in a…
