This paper explores the effects of information sharing on diversity and adaptivity of behaviors in competitive populations. We focus on the information supplement of congestion status at the events or theme parks. We have conducted a multi-agent simulation, in which each agent visiting the attractions is able to avoid the crowded ones by using the shared information among agents with a certain ...

We extend the algebraic approach of Meseguer and Montanari from ordinary place/transition Petri nets to contextual nets, covering both the collective and the individual token philosophy uniformly along the two interpretations of net behaviors.

Many biological systems exhibit collective behaviors that strengthen their adaptability to their environment, compared to more solitary species. Describing these behaviors is challenging yet necessary in order to understand these biological systems. We propose a probabilistic model that enables us to uncover the collective behaviors observed in a colony of ants. This model is based on the assum...

In a companion paper [9] we argued that human economic interactions, particularly bargaining and trading in market environments, can be considered as adaptive behaviors, and that the tools and techniques of adaptive behavior research can be profitably employed in modeling naturally-occUlTing markets or constructing artificial market-based systems. H groups of simple artificial agents interact t...

Collective cell movement is critical to the emergent properties of many multicellular systems, including microbial self-organization in biofilms, embryogenesis, wound healing, and cancer metastasis. However, even the best-studied systems lack a complete picture of how diverse physical and chemical cues act upon individual cells to ensure coordinated multicellular behavior. Known for its social ...

The artificial intervention of biological rhythms remains an exciting challenge. Here, we proposed artificial control strategies that were developed to mediate the collective rhythms emerging in multicellular structures. Based on noisy repressilators and by injecting a periodic control amount to the extracellular medium, we introduced two typical kinds of control models. In one, there are infor...

The suicide rate among American adolescents between the ages of 14-25 has dramatically increased during the last 50 years, and this fact has been the focus of extensive social-scientific investigation. To date, however, research focusing on the joint effects of mental health, family, and contextual-level predictors on adolescents' suicidal behaviors is scarce. Drawing on Durkheim's classic macr...

Collective behaviors in social insect societies often emerge from simple local rules. However, little is known about how these behaviors are dynamically regulated in response to environmental changes. Here, we use a compartmental modeling approach to identify factors that allow harvester ant colonies to regulate collective foraging activity in response to their environment. We propose a set of ...

Mated birds of many species vocalize together, producing duets. Duetting behavior occurs at two levels of organization: the individual level and the pair level. Individuals initiate vocalizations, answer their mates’ vocalizations, and control the structure and timing of their own vocalizations. Pairs produce duets that vary with respect to duration, temporal coordination, and phrase-type combi...

Collective behaviors in social insect societies often emerge from simple local rules. However, only little is known about how these behaviors are dynamically regulated in response to environmental changes. Here, we use a compartmental modeling approach to identify factors that allow social insects to regulate collective foraging activity in response to their environment. We propose a set of dif...
