论文摘要
来自Unuversidad Autonoma de Madrid的研究生班的这些笔记分析了一种被称为区域搜索（ARS）的搜索行为，在动物界中广泛分布，并且当一个人追求的资源是“斑点”的时候。在第一部分中，我们研究了动物行为的重要性及其对多巴胺的依赖性作为奖励的指标。在第二部分中，我们汇总了一种遗传算法，以确定ARS及其特征的最佳性。最后，我们将ARS与称为“ Levy Walks”的一种随机步行相关联，其中与当前位置距离D距离D的概率遵循功率定律分布。
These notes from a graduate class at the Unuversidad Autonoma de Madrid analyze a search behavior known as Area Resticted Search (ARS), widespread in the animal kingdom, and optimal when the resources that one is after are "patchy". In the first section we study the importance of the behavior in animal and its dependence on the dopamine as a indicator of reward. In the second section we put together a genetic algorithm to determine the optimality of ARS and its characteristics. Finally, we relate ARS to a type of random walks known as "Levy Walks", in which the probability of jumping at a distance d from the current location follows a power law distribution.
