The FRW appears to be particularly interesting when applied as random walk based search strategy due to its relationship to anomalous transport and diffusion phenomena and Levy flights. The chapter explains the FRW on periodic and infinite d-dimensional cubic primitive lattices with special focus on recurrence/transience behavior emerging in the infinite lattice limit. It describes basic features of Markovian walks on regular networks. The chapter deals with asymptotic fractal scaling in the transient regime of the set of distinct nodes visited by the fractional walker in an infinitely long walk. It shows that the set of distinct nodes visited constitutes a stochastic fractal of isotropic (spherical) symmetry with respect to the departure node.Read More
