The Lévy flight foraging hypothesis: forgetting about memory may lead to false verification of Brownian motion

摘要

BackgroundThe Lévy flight foraging hypothesis predicts a transition from scale-free Lévy walk (LW) to scale-specific Brownian motion (BM) as an animal moves from resource-poor towards resource-rich environment. However, the LW-BM continuum implies a premise of memory-less search, which contradicts the cognitive capacity of vertebrates.
