寻找食物、配偶或家园的动物通常需要决定何时停止寻找，并选择迄今为止找到的最佳选择。通过重新分析Mallon等人的实验数据（Behav Ecol Sociobiol 50：352-359，2001），我们证明了寻屋蚁群在迁移过程中逐渐更加致力于新的巢穴。在寻找巢穴的早期，蚂蚁个体会灵活地选择新的巢穴。然而，当搬运到一个新的巢穴开始时，蚂蚁几乎不会改变偏好。使用基于实验数据的理论模型，我们测试在哪个阶段的灵活承诺影响速度和准确性最大。我们证明了蚁群在不耐烦和拖延之间找到了一个很好的折衷。早期的灵活性与后来的刚性相结合，与其他包括灵活承诺的战略一样有效，但在移民条件恶劣时尤其有效。
Animals searching for food, mates, or a home often need to decide when to stop looking and choose the best option found so far. By re-analyzing experimental data from experiments by Mallon et al. (Behav Ecol Sociobiol 50:352-359, 2001), we demonstrate that house-hunting ant colonies are gradually more committed to new nests during the emigration. Early in house-hunting, individual ants were flexibly committed to new nest sites. However, when carrying to a new nest had started, ants hardly ever switched preference. Using a theoretical model based on experimental data, we test at which stage flexible commitment influences speed and accuracy most. We demonstrate that ant colonies have found a good compromise between impatience and procrastination. Early flexibility combined with later rigidity is identically effective as other strategies that include flexible commitment, but it is particularly good when emigration conditions are harsh.
