CSE200 Lecture Notes – Immerman-Szelepcsényi Theorem

Witryna6 paź 2024 · In this paper we give an Immerman Theorem for real-valued computation, i.e., we define circuits of unbounded fan-in operating over real numbers and show that families of such circuits of polynomial size and constant depth decide exactly those sets of vectors of reals that can be defined in first-order logic on \mathbb {R} -structures in … WitrynaProof sketch []. The theorem can be proven by showing how to translate any nondeterministic Turing machine M into another nondeterministic Turing machine that … The compression theorem is an important theorem about the complexity of computable functions. The theorem states that there exists no largest complexity class, with computable boundary, which contains all computable functions. The space hierarchy theorems are separation results that show that both deterministic and nondeterministic machines can solve more problems in (asymptotically) more space, subject to … dakine westside insulated snow pants
