Chapter 8: Implications for Everyday Systems

Section 1: Issues of Modelling

Consequences of models

Given a program it is always possible to run the program to find out what it will do. But as I discuss in Chapter 12, when the behavior is complex it may take an irreducible amount of computational work to answer any given question about it. However, this is not a sign of imperfection in the model; it is merely a fundamental feature of complex behavior.
