WebSep 15, 2024 · Lévy walks are a special class of random walks with step lengths ℓ that follow a power-law distribution P (ℓ) ∼ ℓ − μ where μ ∈ (1,3] is a power-law exponent. Lévy walks are observed in a variety of biological movements and agents, ranging from cells and insects to mammals, humans, and even memory retrievals in human cognition ( 1 – 8 ).
