Abstract

Researchers have shown that self-assembly of tile-like DNA structures can be used for nanoscale computations. The abstract Tile Assembly Model (aTAM), proposed by Winfree in 1998, is a simple mathematical abstraction of DNA tile self-assembly. The aTAM is extensively studied in the past 15 years. In this talk, I will give a brief overview of complexity results for the aTAM, show how allowing nondeterminism can increase the power of the aTAM even in self-assembling a shape deterministically, and finally discuss a number of open questions.
