相互作用种群中的最优搜索:高斯跳跃与Levy飞行

Optimal search in interacting populations:Gaussian jumps vs Levy flights

Ricardo Martinez-Garcia, Justin M. Calabrese, Cristobal Lopez

摘要:

我们研究了搜索效率,运动策略和非本地通信的动物觅食的生物背景之间的关系。我们考虑的情况下,觅食的人口的成员进行高斯跳跃或利维飞行,并表明,搜索时间最小化时,个人之间的通信发生在中间范围内,独立的运动类型。此外,虽然布朗策略更强烈的影响,沟通机制,利维飞行仍然导致较短的整体搜索时间。

英文摘要:

We investigated the relationships between search efficiency, movement strategy, and non-local communication in the biological context of animal foraging. We considered situations where the members of a population of foragers perform either Gaussian jumps or Levy flights, and show that the search time is minimized when communication among individuals occurs at intermediate ranges, independently of the type of movement. Additionally, while Brownian strategies are more strongly influenced by the communication mechanism, Levy flights still result in shorter overall search durations.
