Efficient Logspace Classes for Enumeration, Counting, and Uniform Generation
Summary: Two logspace classes via NL transducers: unambiguous class gives constant‑delay enumeration plus polytime exact counting and uniform generation. Unrestricted class gives poly‑delay enumeration, an FPRAS for counting and polytime Las Vegas uniform generation by proving #NFA (thus all SpanL) admits an FPRAS.
