Abstract

We prove the unique assembly and unique shape verification problems, benchmark measures of self-assembly model power, are \(\textsf {coNP}^{\textsf {NP}}\)-hard and contained in PSPACE (and in \(\mathrm {\Pi }^\textsf {P}_{2s}\) for staged systems with s stages). En route, we prove that unique shape verification problem in the 2HAM is \(\textsf {coNP}^{\textsf {NP}}\)-complete.

Fußnoten
1
The original staged model (Demaine et al. 2008) only considered O(1) distinct tile types, and thus for simplicity allowed tiles to be added at any stage (since \(\mathcal {O}(1)\) extra bins could hold the individual tile types to mix at any stage). Because systems here may have super-constant tile complexity, we restrict tiles to only be added at the initial stage.
 
2
This is a slight modification of the original staged model (Demaine et al. 2008) in that there is no requirement of a final stage with a single output bin. This may be a slightly more capable model, and so it is considered here. However, all results in this paper apply to both variants of the model.
