Search efficiency of discrete fractional Brownian motion in a random distribution of targets

In foraging for food, biological organisms explore terrain in search of irregularly dispersed sources. Mathematically, such foraging processes can be modelled using stochastic processes, and in the simplest paradigm – Gaussian spreading generated by random walks or Brownian motion – the mean square displacement of an ensemble of moving agents grows linearly in time.
