Towards Practical FPRAS for #NFA: Exploiting the Power of Dependence
Summary: Proposes a practical FPRAS for #NFA with time O(n^2 m^3 log(nm) eps^-2 log(delta^-1)). Sub-quadratic membership checks (O(n m^2)) enable tractable counting of length-n words accepted by NFAs, addressing impractical prior FPRAS. (summarized by gpt-5-nano on Feb 09 2026)
