abstract = { Lévy flights are known to be optimal search strategies in the particular case of revisitable targets. In the
relevant situation of nonrevisitable targets, we propose an alternative model of two-dimensional 2D search
processes, which explicitly relies on the widely observed intermittent behavior of foraging animals. We show
analytically that intermittent strategies can minimize the search time, and therefore do constitute real optimal
strategies. We study two representative modes of target detection and determine which features of the search
time are robust and do not depend on the specific characteristics of detection mechanisms. In particular, both
modes lead to a global minimum of the search time as a function of the typical times spent in each state, for
the same optimal duration of the ballistic phase. This last quantity could be a universal feature of 2D inter-
mittent search strategies.
