Determinism and Non-determinism in NetLogo
NetLogo is designed to mimic a parallel processing system, although it is fundamentally a serial processing one. For example, when a set of agents are asked to run a command, the agents must be sequentially asked because they cannot be asked simultaneously. This feature of NetLogo can be used to illustrate deterministic processes as well as to mimic non-deterministic ones.

The world as we perceive it is neither fully disorganized (Figure 1), beyond our ability to identify any overall pattern in it, nor fully organized, describable by us in terms of some single simple pattern (Figure 2). Instead, we are faced with, and find ourselves trying to make sense of, a world that most typically shows mixes of pattern and disorganization at different scales (Figures 3, 4, 5).
