Can a problem be in NP complexity class if there is a non deterministic turing machine that will solve it in polynomial time
The question "Can a problem be in NP complexity class if there is a non-deterministic Turing machine that will solve it in polynomial time?" touches upon fundamental concepts in computational complexity theory. To address this question comprehensively, we must consider the definitions and characteristics of the NP complexity class and the role of non-deterministic Turing
NP is the class of languages that have polynomial time verifiers
The class NP, which stands for "nondeterministic polynomial time," is a fundamental concept in computational complexity theory, a subfield of theoretical computer science. To understand NP, one must first grasp the notion of decision problems, which are questions with a yes-or-no answer. A language in this context refers to a set of strings over some

What are the open questions regarding the relationship between BQP and NP, and what would it mean for complexity theory if BQP is proven to be strictly larger than P?
The relationship between BQP (Bounded-error Quantum Polynomial time) and NP (Nondeterministic Polynomial time) is a topic of great interest in complexity theory. BQP is the class of decision problems that can be solved by a quantum computer in polynomial time with a bounded error probability, while NP is the class of decision problems that can
How do we convert a problem in NP into an instance of the satisfiability problem?
The process of converting a problem in NP (Nondeterministic Polynomial time) into an instance of the satisfiability problem (SAT) involves transforming the original problem into a logical formula that can be evaluated by a SAT solver. This technique is a fundamental concept in computational complexity theory and plays a important role in proving that SAT
What is the definition of the class NP in the context of computational complexity theory?
The class NP, in the context of computational complexity theory, plays a important role in understanding the complexity of computational problems. NP stands for Nondeterministic Polynomial time, and it is a class of decision problems that can be efficiently verified by a nondeterministic Turing machine in polynomial time. In other words, NP represents the set
Explain the two equivalent definitions of the class NP and how they relate to polynomial time verifiers and non-deterministic Turing machines.
In the field of computational complexity theory, the class NP (Non-deterministic Polynomial time) is a fundamental concept that plays a important role in understanding the complexity of computational problems. There are two equivalent definitions of NP that are commonly used: the polynomial time verifier definition and the non-deterministic Turing machine definition. These definitions provide different
What is polynomial verifiability and how does it relate to the class NP?
Polynomial verifiability is a concept in computational complexity theory that plays a important role in the study of the complexity class NP. To understand polynomial verifiability, we must first grasp the definition of NP. NP, which stands for "nondeterministic polynomial time," is a class of decision problems that can be verified in polynomial time. In
What is the language of a grammar?
A grammar is a formal system used to describe the structure and composition of a language. In the field of computational complexity theory, specifically in the study of context-free grammars and languages, the language of a grammar refers to the set of all possible strings that can be generated by that grammar. The language is
