通过伙伴选择机制的合作的演变通常被认为涉及相对复杂的认知能力。使用基于代理的模拟，我建模了一个简单的合作伙伴选择规则，即“走开”规则，其中个人留在提供更高回报的群体中（凭借拥有更多合作者），而“走开”则离开提供低回报的群体。在公共产品博弈中实施这一条件运动规则会导致一些有趣的发现：1）当阈值高时，合作者具有选择性优势，对应于对背叛者的低容忍度，2）高阈值导致高的初始运动速率和低的最终运动速率（在选择之后），以及3）当选择合作时，人口经历了从高迁移率（以及许多小型和短暂的群体）向低迁移率（以及大型和稳定的群体）的空间转变。这些结果表明，离开不合作群体的非常简单的“走开”规则可以促进合作的进化，并且合作可以在个体能够根据当地社会条件移动的群体中进化。各种各样的生物体能够离开退化的物理或社会环境。条件运动的普遍存在的性质表明，“走开”的动态可能在认知复杂和认知简单的生物体的社会行为的进化中发挥重要作用。
The evolution of cooperation through partner choice mechanisms is often thought to involve relatively complex cognitive abilities. Using agent-based simulations I model a simple partner choice rule, the ‘Walk Away’ rule, where individuals stay in groups that provide higher returns (by virtue of having more cooperators), and ‘Walk Away’ from groups providing low returns. Implementing this conditional movement rule in a public goods game leads to a number of interesting findings: 1) cooperators have a selective advantage when thresholds are high, corresponding to low tolerance for defectors, 2) high thresholds lead to high initial rates of movement and low final rates of movement (after selection), and 3) as cooperation is selected, the population undergoes a spatial transition from high migration (and a many small and ephemeral groups) to low migration (and large and stable groups). These results suggest that the very simple ‘Walk Away’ rule of leaving uncooperative groups can favor the evolution of cooperation, and that cooperation can evolve in populations in which individuals are able to move in response to local social conditions. A diverse array of organisms are able to leave degraded physical or social environments. The ubiquitous nature of conditional movement suggests that ‘Walk Away’ dynamics may play an important role in the evolution of social behavior in both cognitively complex and cognitively simple organisms.
