Log-size Parabolic Clique Problem is a version of Clique Problem solvable in linear time by a log-space nondeterministic Turning machine. However, no deterministic machine (in a very general sense of this term) with sequential-access read-only input tape and work space n s solves Log-size Parabolic Clique Problem within time n 1 + τ if s + 2τ
