Lévy flight foraging hypothesis - Wikipedia

The movement of animals closely resembles in many ways the random walks of dust particles in a fluid. This similarity led to interest in trying to understand how animals move via the analogy to Brownian motion. This conventional wisdom held until the early 1990s. However, starting in the late 1980s, evidence began to accumulate that did not fit the theoretical predictions. In 1999, a theoretical investigation of the properties of Lévy flights showed that an inverse squar… Weblevy: [noun] the imposition or collection of an assessment. an amount levied. in conclusion spanishWebSep 12, 2024 · where LF denotes the levy flight function, UB and LB the bounds of the search space, respectively. s l e a d e r is the random agent.
