Abstract

Intermittent search processes are widely observed in nature and in social activities. Simplified models show that they can be very efficient. Here we give new evidences of this efficiency. We discuss the conditions which can make intermittence favorable to the search, generally due to the imperfection of the detectors. We show that organized strategies, which are possible for searchers with sufficient abilities, in principle lead to shorter search times than random behaviors. Nevertheless, their advantage is not determinant, and random can be practically preferable because of its easier and more general use.
