Center node: "more tight bounds for active self assembly using an insertion primitive"
  Abstract: We prove several limits on the behavior of a model of self-assembling particles introduced by Dabby and Chen (SODA 2013), called insertion systems, where monomers insert themselves into the middle of a growing linear polymer. First, we prove that the expressive power of these systems is equal to context-free grammars, answering a question posed by Dabby and Chen. #R##N#Second, we give tight bounds on the maximum length and minimum expected time of constructed polymers in systems of three increasingly restricted classes. We prove that systems of $k$ monomer types can deterministically construct polymers of length $n = 2^{\Theta(k^{3/2})}$ in $O(\log^{5/3}(n))$ expected time. We also prove that if non-deterministic construction of a finite number of polymers is permitted, then the expected construction time can be reduced to $O(\log^{3/2}(n))$ at the trade-off of decreasing the length to $2^{\Theta(k)}$. If the system is allowed to construct an infinite number of polymers, then constructing polymers of unbounded length in $O(\log{n})$ expected time is possible. We follow these positive results with a set of lower bounds proving that these are the best possible polymer lengths and expected construction times.
