Both from these scanty data and from an examination of the postulates of the economic models it appears probable that, however adaptive the behavior of organisms in learning and choice situations, this adaptiveness falls far short of the ideal of “maximizing” postulated in economic theory. Evidently, organisms adapt well enough to “satisfice”; they do not, in general, “optimize.”

That’ll do. A pragmatic alternative where you cannot achieve the optimum so settle for something sufficiently satisfactory that no one complains enough to leave. Technically, you either simplify your model and optimise for that simplified model even though it doesn’t quite fit in every case, or you keep the intractable world and lower your threshold for solving whatever your problem is.
Humans, not really having a choice, do this all the time. It explains Marks & Spencer.
