RL and ZPL
Hi there, welcome to Wikipedia and thanks for your feedback on NL (complexity). When I wrote this I was referring not to the polynomial-time restricted versions of RL and ZPL, which a lot of people call RL and ZPL, but the unrestricted-time versions, which rather trivially equal NL (Complexity Zoo says in its RL entry "It must also run in polynomial time (since otherwise we would just get NL).") I read the same of ZPL in a lecture by Oded Goldreich linked on the RL page (I think). This is a pretty frequent source of confusion, and I'm unsure whether I should even refer to the unrestricted-time versions of RL and ZPL. Deco 22:54, 6 January 2006 (UTC)
