Informal Description
An assembly generally refers to the structure created from tiles binding together.
Definition
An assembly in \(n\)-dimensional space (most commonly taken to be \(n=2\) or \(n=3\)) is a partial function \({\alpha}:{\mathbb{Z}^n} \dashrightarrow {T}\).
Tau-stable Assembly
An assembly is \(\tau\)-stable if it cannot be broken up into smaller assemblies without breaking bonds of total strength at least \(\tau\) for some \(\tau \in \mathbb{N}\). For example, in models such as the Abstract Tile Assembly Model (aTAM) and the Two-Handed Assembly Model (2HAM) all assemblies are \(\tau\) stable where \(\tau\) is the Temperature of the system, but in models such as the Kinetic Tile Assembly Model (kTAM) there can exist an assembly that is not \(\tau\)-stable.
Seed Assembly
In a seeded tile assembly model, a seed assembly refers to the initial structure from which growth begins.
