Cooperation

Overview

Cooperation is a property of systems that can take information from two different places in order to determine which tiles to place in a third location. Cooperation is important because it enables tile assembly systems to simulate Turing machines and, by extension, perform universal computations. This is traditionally a property of temperature 2 or higher systems, since this enables single tiles to have certain glues that allow them to attach in place based off of the exposed glues nearby. However, temperature 1 systems have been known to "fake" cooperation using geometry in certain augmentations of the model.
