On the metamathematics of the P vs. NP question
We review the work (from 1976 to 1996) by several researchers on the metamathematics of P vs. NP. That work points towards the possibility that, given some strong consistent axiomatic system S with a recursively enumerable set of theorems which includes arithmetic, for the R2 sentence 1⁄2P 1⁄4 NP that formalizes the P 1⁄4 NP hypothesis, S þ 1⁄2P 1⁄4 NP is consistent. We consider the work of sev...
متن کاملA review of the biological characteristics of ornamental and exotic giant snakeheadexotic, Channa micropeltes (Cuvier, 1831), reported from Anzali Wetland
The present work was conducted to study the biological characteristics of giant snakehead, Channa micropeltes, a popular ornamental species in the world. This species is native to Southeast Asia and also is distributed in Thailand, Laos (Mekong Basin), Vietnam, Malaysia, Sumatra (Bangka and Belitung Islands), Kalimantan and northern Java. Among the environmental characteristics, vegetation play...
متن کامل2 P vs . NP and Diagonalization
2.1 3SAT is NP–hard Definition 2.1 (the class NP). L ⊂ {0, 1}∗ is in the class of NP if there exists a polynomial p : N→ N and a Turing machine M (called the verifier for L) such that for every x ∈ {0, 1}∗, x ∈ L ⇔ ∃y ∈ {0, 1}p(|x|) such that M(x, y) = 1. If x ∈ L and y ∈ {0, 1}p(|x|) satisfy M(x, y) = 1, then we call y a certificate/witness for x (with respect to the language L and machine M)....
متن کاملA Proof for P =? NP Problem
The P =? NP problem is an important problem in contemporary mathematics and theoretical computer science. Many proofs have been proposed to this problem. This paper proposes a theoretic proof for P =? NP problem. The central idea of this proof is a recursive definition for Turing machine (shortly TM) that accepts the encoding strings of valid TMs. By the definition, an infinite sequence of TM i...
متن کاملMethodology of conceptual review in the health system
Background: Conceptual review is a creative research method for generating new knowledge in the context of a vague and complex concept that helps to explain and clarify the concept, its components and its relation to related concepts. This study aimed to explain the methodology of conceptual review in the health system. Methods: Articles related to the conceptual research method were searched ...
