Levy Flight Searches in the Foraging Behaviour of Ants
The foraging movements of Iridomyrmex species of ant are observed to follow a Levy flight distribution. The movement step size is shown to be characterised by a power law distribution. This makes the movement fractal in nature, which will produce an efficient search pattern. Introduction: Levy flights are a category of random walks first devised by Paul Levy in 1937 by generalizing Brownian mot...
متن کاملEvidence of Levy walk foraging patterns in human hunter-gatherers.
When searching for food, many organisms adopt a superdiffusive, scale-free movement pattern called a Lévy walk, which is considered optimal when foraging for heterogeneously located resources with little prior knowledge of distribution patterns [Viswanathan GM, da Luz MGE, Raposo EP, Stanley HE (2011) The Physics of Foraging: An Introduction to Random Searches and Biological Encounters]. Althou...
متن کاملClustering Using Levy Flight Cuckoo Search
In this paper, a comparative study is carried using three nature-inspired algorithms namely Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Cuckoo Search (CS) on clustering problem. Cuckoo search is used with levy flight. The heavy-tail property of levy flight is exploited here. These algorithms are used on three standard benchmark datasets and one real-time multi-spectral satelli...

متن کاملLevy model of cancer
Along an individual lifetime, stem cells replicate and suffer modifications in their DNA content. I model the modifications in the DNA of a single cell as a Levy flight, made up of small amplitude Brownian motions plus rare large-jumps events. The distribution function of mutations has a long tail, in which cancer events are located far away. The probability of cancer in a given tissue is rough...
