Query: Application of planar Randers geodesics with river-type perturbation in
  search models   We consider remodeling the planar search patterns, in the presence of the
river-type perturbation represented by the weak vector field, basing on the
time-optimal paths as Finslerian solutions to the Zermelo navigation problem
via Randers metric.
