Abstract Tile Assembly Model ( Erik Winfree, PhD thesis 1998) (DNA) tile self-assembly -- DNA tile = unit square -- each side has a glue strength (0, 1, 2) -- finite number of tile types -- tiles join together if their glues match -- binding is stable if total strength ≥ a threshold TPNC, 2014 Seed tile Boundary tiles Rule tiles Tile set for a sierpinski pattern self-assembly OR L-shaped seed structure 04
