Problem Definition
In the theory of molecular-scale self-assembly, large numbers of simple interacting components are designed to come together to build complicated shapes and patterns. Many models of self-assembly, such as the abstract Tile Assembly Model [6], are cellular automata-like crystal growth models. Indeed such models have given rise to a rich theory of self-assembly as described elsewhere in this encyclopedia. In biological organisms we frequently see much more sophisticated growth processes, where self-assembly is combined with active molecular components that change internal state and even molecular motors that have the ability to push and pull large structures around. Molecular engineers are now beginning to design and build molecular-scale DNA motors and active self-assembly systems [2]. We wish to...
