论文摘要
我们提出了动物竞赛时空动力学的一般理论模型。受物理粒子之间的相互作用的启发，该模型是根据有效的相互作用电位提出的，这些互动电位将比赛行为的典型要素映射到参赛者运动的经验可验证的规则中。这使我们能够模拟各种现实场景中的竞赛动态，特别是在局部资源的二元比赛中。以前在游戏理论模型中制定的评估策略以及战斗成本的影响可以描述为我们模型参数的变化。此外，可以在模型中得出和理解与这些评估策略相关的比赛持续时间的趋势。参赛者运动的详细描述可以探索不对称竞赛的时空特性，例如Chase Dynamics的出现。总体而言，我们的框架旨在在动物行为的这一广泛方面弥合经验能力与理论之间日益增长的差距。
We present a general theoretical model for the spatio-temporal dynamics of animal contests. Inspired by interactions between physical particles, the model is formulated in terms of effective interaction potentials, which map typical elements of contest behaviour into empirically verifiable rules of contestant motion. This allows us to simulate the observable dynamics of contests in various realistic scenarios, notably in dyadic contests over a localized resource. Assessment strategies previously formulated in game-theoretic models, as well as the effects of fighting costs, can be described as variations in our model's parameters. Furthermore, the trends of contest duration associated with these assessment strategies can be derived and understood within the model. Detailed description of the contestants' motion enables the exploration of spatio-temporal properties of asymmetric contests, such as the emergence of chase dynamics. Overall, our framework aims to bridge the growing gap between empirical capabilities and theory in this widespread aspect of animal behaviour.
