ABSTRACT The authors propose a new predator–prey game model by integrating two optional strategies into prey species: cooperative and isolation strategies. An investigation of the evolutionary impact on system dynamics is given. utilizes replicator equation to track changes in frequency strategy among preys, along with population growth equations detailing variations predator biomass. Interestingly, both isolated can coexist within species. As predation rate increases, preys are more inclined adopt strategies, thereby boosting Abundant resources then encourage opt for secure defend against predators. Under specific conditions, exhibits intricate involving bistability, transcritical, Hopf bifurcations. A novel fractional‐order derived using continuous‐time random walk based potential physical stochastic process, which different than traditional models. influence fractal dimension analyzed, showing that it either diminish or eliminate species potentially lead extinction. affects convergence speed without altering its final steady state: time change, adopted biomasses prey, ultimately stabilize toward same state, but their rates approaching state different. In this case, only survive These models have multiple applications settings, aiding management animal populations, pest control, tumor immune interactions, infectious diseases.

Abstract There exists an important connection between the development of sports economy and spatial characteristics, but current characteristics economic linkages suffers from lack identification screening subjects interest inability to articulate structure interests each subject. The article adopts research paradigm based on rooted theory encode game phenomenon constructs evolutionary model that integrates administrative regulator, supply side community public services, demand side. optimal equilibrium strategy promote sustainable urban services governance is also explored by combining Jacobian matrix simulation experiments. Although tripartite play different dynamic roles at stages transformation, they all converge steady state (1, 1, 1) in end. In addition, three have processes. First, probability choosing support core area decreases then rises, while government mass recognition both increase. area, support, are experiencing a gradual Finally, shows first decline rise, continues show increase, finally evolve into state.
