Abstract

Herbert Simon once observed that watching an ant make its way across the uneven surface of a beach, one can easily be impressed—too impressed—with the foresight and complexity of the ant's internal map of the beach. Simon went on to point out that such an attribution of complexity to the ant makes a serious mistake. Most of the complexity is not in the ant but in the beach. The ant is just complex enough to use the features of the beach to find its way.
