Levy Foraging in a Dynamic Environment – Extending the Levy Search

Abstract: A common task for robots is the patrolling of an unknown area with inadequate information about target locations. Under these circumstances it has been suggested that animal foraging could provide an optimal or at least suboptimal search methodology, namely the Levy flight search. Although still in debate, it seems that predators somehow follow this search pattern when foraging, because it avoids being trapped in a local search if the food is beyond the sensory range. A Levy flight is a particular case of the … Show more

“…LW statistics were shown to characterise human hunter-gatherer foraging [17], pedestrian movement [18], human movement patterns [19] as well as COVID-19 pandemic propagation [20], and they were shown to emerge in optimised robotic search [21]. More microscopically, LWs were observed for the motion of individual molecular motors in living biological cells [22] and for the motor-driven transport of single messenger RNA molecules in live dendritic cells [23].…”

“…The traditional one is with constant speed and the corresponding running time for each step follows the distribution . Lévy walk is observed in many fields, such as molecular-motor motion [ 13 , 61 ], human hunter-gatherer foraging [ 55 ], optimized robotic search [ 23 ], as well as the propagation of COVID-19 pandemic [ 27 ].…”
