This paper presents results and observations from the authors' continuing explorations of EC systems where population members act as autonomous agents that conduct their own, independent evaluation of (and reproduction with) other agents. In particular, we consider diversity preservation in one such agent-based EC system, applied to the multi-peak functions often used to illustrate and evaluate the effects of fitness-sharing-like schemes in GAs. We show how (somewhat surprisingly) mating restriction alone yields stable niching in agent-based EC. This leads to a consideration of niching as a generalized phenomenon, and the introduction of niching pressure as a concept that parallels selective pressure, and which can yield insight. The utility of the niching pressure concept for general EC is explored, and directions for further research are discussed.
