Bounded Queries, Approximations and the Boolean Hierarchy

Revisions: 1

This paper introduces a new model of computation for describing the
complexity of NP-approximation problems. The results show that the
complexity of NP-approximation problems can be characterized by classes of
multi-valued functions computed by nondeterministic polynomial time Turing
machines with a bounded number of oracle queries to an NP-complete
language. ... more >>>
