摘要
How to best exploit patchy resources? We introduce a minimal exploitation-migration model that incorporates the coupling between a searcher's trajectory, modeled by a randomwalk, and ensuing depletion of the environment by the searcher's consumption of resources. The searcher also migrates to a new patch when it takes S consecutive steps without finding resources. We compute the distribution of consumed resources F-t at time t for this non-馬可夫ian searcher and show that consumption is maximized by exploring multiple patches. In one dimension, we derive the optimal strategy to maximize F-t. This strategy is robust with respect to the distribution of resources within patches and the criterion for leaving the current patch. We also show that F-t has an optimum in the ecologically relevant case
