Abstract
A generalized reduction sub-exponential reduction family (SERF) is developed that preserves sub-exponential complexity. It is shown that Circuit-SAT is SERF-complete for all NP-search problems, and that for any fixed k, k-SAT, k-colorability, k-set cover, independent set, clique, vertex cover, are SERF-complete for the class SMP of search problems expressible by second order existential formulas whose first order part is universal.
