Evolutionary dynamical models for cyclic competitions of three species (e.g., rock, paper and scissors, or RPS) provide a paradigm, at the microscopic level individual interactions, to address many issues in coexistence biodiversity. Real ecosystems often involve among more than species. By extending RPS game model five (rock-paper-scissors-lizard-Spock, RPSLS) mobile species, we uncover fundamental type mesoscopic interactions subgroups In particular, lead emergence various local groups...
The existence of neutral species carries profound ecological implications that warrant further investigation. In this paper, we study the impact on biodiversity in a spatial tritrophic system cyclic competition, which are identified as fourth may affect competition process other three under rock-paper-scissors (RPS) rule. Extensive simulations showed can promote coexistence high mobility regime within system. When occurs, found state be maintained by two mechanisms: Species either (i) adhere...
Evolutionary games of cyclic competitions have been extensively studied to gain insights into one the most fundamental phenomena in nature: biodiversity that seems be excluded by principle natural selection. The Rock-Paper-Scissors (RPS) game three species and its extensions [e.g., Rock-Paper-Scissors-Lizard-Spock (RPSLS) game] are paradigmatic models this field. In all previous studies, intrinsic symmetry associated with imposes a limitation on resulting coexistence states, leading only...
Complex networks are widespread in real-world environments across diverse domains. Real-world tend to form spontaneously through interactions between individual agents. Inspired by this, we design an evolutionary game model which agents participate a prisoner’s dilemma (PDG) with their neighboring Agents can autonomously modify connections neighbors using reinforcement learning avoid unfavorable environments. Interestingly, our findings reveal some remarkable results. Exploiting...

Investment in resources is essential for facilitating information dissemination real-world contexts, and comprehending the influence of resource allocation on is, thus, crucial efficacy collaborative networks. Nonetheless, current studies frequently fail to clarify complex interplay between distribution network contexts. In this work, we establish a resource-based model identify by examining propagation threshold equilibriums. We assess model’s juxtaposing mean-field method with Monte Carlo...
The main goal of this paper is to study how a decision-making rule for vaccination can affect epidemic spreading by exploiting the Bush–Mosteller (BM) model, one methodologies in reinforcement learning artificial intelligence (AI), which realize systematic process humans, on complex networks. We consider BM model with two stages—vaccination and epidemiological processes—and address independent rules about fixed loss consideration average payoff neighbors update agent’s behavior various...
A fundamental result in the evolutionary-game paradigm of cyclic competition spatially extended ecological systems, as represented by classic Reichenbach-Mobilia-Frey (RMF) model, is that high mobility tends to hamper or even exclude species coexistence. This was obtained under hypothesis individuals move randomly without taking into account suitability their local environment. We incorporate habitat RMF model and investigate its effect on In particular, we hypothesize use "basic instinct"...
Cyclically competition models have been successful to gain an insight of biodiversity mechanism in ecosystems. There are, however, still limitations elucidate complex phenomena arising real competition. In this paper, we report that a multistability occurs simple rock-paper-scissor cyclically model by assuming intraspecific depends on the logistic growth each species density. This stability is absent any model, and investigate how proposed affects existing society three through macroscopic...

Understanding mechanisms which promote or hinder existing ecosystems are important issues in ecological sciences. In addition to fundamental interactions such as competition and migration among native species, can be easily disturbed by external factors, the emergence of new species may an example cases. The does not exist a current ecosystem regarded either alien entered from outside mutant born mutation normal species. Recently, getting influenced various physical/chemical due...
We study the spatial rock-paper-scissors game with adaptive mutation which may describe imitation behaviors of two competing species. introduce an where one species tend to mutate other by implementing a fundamental mechanism respect local fitness comparing payoffs its origin updated when it mutates other. By means Monte Carlo simulations, we show that coexistence can be promoted intensification at certain high mobility regimes lead extinction traditionally, even if extremely results in as...
Alternative strategy is common in animal populations to promote reproductive fitness by obtaining resources. In spatial dynamics of cyclic competition, reproduction can occur when individuals obtain vacant rooms and, this regard, empty sites should be resources for which induced interspecific competition. paper, we study the role alternative competition system cyclically competing five species utilizing rock-paper-scissors-lizard-spock game. From Monte-Carlo simulations, found that strong...
Abstract Recognizing territories is essential to decide behavior of population either human or animals, and interaction between groups individuals according the territorial awareness universal. Understanding various mechanisms which affect on such species behaviors can be possible by evolutionary games, in particular, rock–paper–scissors (RPS) game has been played a key role as paradigmatic model explore biodiversity from microbiota societies. Among paramount systems RPS, intraspecific...
We investigate evolving dynamics of cyclically competing species on spatially extended systems with considering a specific region, which is called the “wildlife refuge,” one institutional ways to preserve biodiversity. Through Monte-Carlo simulations, we found that refuge can play not groundbreaking but an important role in survival. Species coexistence maintained at moderate mobility regime, traditionally leads collapse coexistence, and eventually, extinction postponed depending competition...
