Center node: "simulation of self assembly in the abstract tile assembly model with isu tas"
  Abstract: Since its introduction by Erik Winfree in 1998, the abstract Tile Assembly Model (aTAM) has inspired a wealth of research. As an abstract model for tile based self-assembly, it has proven to be remarkably powerful and expressive in terms of the structures which can self-assemble within it. As research has progressed in the aTAM, the self-assembling structures being studied have become progressively more complex. This increasing complexity, along with a need for standardization of definitions and tools among researchers, motivated the development of the Iowa State University Tile Assembly Simulator (ISU TAS). ISU TAS is a graphical simulator and tile set editor for designing and building 2-D and 3-D aTAM tile assembly systems and simulating their self-assembly. This paper reviews the features and functionality of ISU TAS and describes how it can be used to further research into the complexities of the aTAM.
