SpletIn computational complexity theory, an interactive proof system is an abstract machine that models computation as the exchange of messages between two parties: a prover and a … Splet17. feb. 2024 · Drugs with legitimate medical uses (like Adderall) would be available; drugs without medical uses (like PCP) would not. Two things change: (1) research gets easier and (2) DEA, a law enforcement agency, doesn’t get to decide whether and when drugs have “accepted medical uses.”. Abolishing Schedule I may seem radical.
Splet1. In order to formalize the notion of a probabilistically checkable proof, we start with a bare- bones (computationally simplified) view of logic.

Splet19. apr. 2024 · The PCP theorem says that there is a proof format (a way of writing proofs in support of an assertion) quite distinct from the usual proof format encountered in mathematics and elsewhere. This proof format allows a verifier to read a constant number of bits from random spots in a proof, do some simple computations, and make an … Splet15. dec. 2010 · The goal of Dinur's proof is to prove that the gap CSP problem is NP-hard, and this problem is equivalent to the PCP theorem. In the proof of this equivalence, the PCP query complexity corresponds to the arity of the CSP. $\endgroup$ – …

In fact, we have the following stronger result: Lemma 1 PCP(log;poly) = NP. Proof Containment of NP in PCP(log;poly) is obvious.
