We study the adaptive behavior of a computational ecosystem in the presence of time-periodic resource utilities as seen, for example, in the day-night load variations of computer use and in the price fluctuations of seasonal products. We do so within the context of the Huberman-Hogg model of such systems. The dynamics is studied for the cases of competitive and cooperative payoff functions with time-modulated resource utilities, and the system's adaptability is measured by tracking its performance in response to a time-varying environment.

Keywords: non-linear dynamics, distributed computation, adaptability.
