Before revision: The benefit of chemokinesis in motile cells, i.e., the regulation of speed and directional persistence as function of spatial position by non-directional cues, is not well understood. We develop a theory of chemokinetic search agents that can detect the proximity of hidden targets and adapt their motility in a position-dependent manner.
