Levy flight search patterns of wandering albatrosses

Article Abstract:

The foraging behavior of the wandering albatross Diomedea exulans in the South Atlantic Ocean, can be studied from the quantitative analyses of Levy flight search patterns. Levy flights are random walks with irregular step lengths. Quantitative analyses regarding the flight-time intervals of the wandering albatross gives the power-law distribution. Biological search problems in complex environments may be addressed with the Levy flight search patterns. The one-parameter Levy flight model for foraging, used in studying the scale invariance is described.

Optimizing the success of random searches

Article Abstract:

The best statistical strategy required to search efficiently for randomly located objects was sought. The way in which the search efficiency depends on the probability distribution of flight lengths taken by a forager that detects target sites in its vicinity, is studied. When target sites are sparse and are visited any number of times, it was found that an inverse square power-law distribution of flight lengths, linking to Levy flight motions, is the optimal strategy.

Revisiting Levy flight search patterns of wandering albatrosses, bumblebees and deer

Article Abstract:

The results from re-analysis of high-resolution data set of wandering albatross flights of deer and bumblebees, which shows no evidence for Levy flight behavior, are discussed.
