## What is the meaning of ZPP?

zero-error probabilistic polynomial time

In complexity theory, ZPP (zero-error probabilistic polynomial time) is the complexity class of problems for which a probabilistic Turing machine exists with these properties: It always returns the correct YES or NO answer. The running time is polynomial in expectation for every input.

**What is pp problem?**

In complexity theory, PP is the class of decision problems solvable by a probabilistic Turing machine in polynomial time, with an error probability of less than 1/2 for all instances. The abbreviation PP refers to probabilistic polynomial time. The complexity class was defined by Gill in 1977.

**What is PP and NP?**

Acronym. Definition. NP/PP. Network Provider/Print Provider.

### What are the four complexity classes involving randomized algorithms?

We describe 4 complexity classes: RP (stands for Randomized Complexity), CoRP (complement of RP), BPP (stands for Bounded-error Probabilistic Polynomial time), and ZPP (stands for Zero-error Prob- abilistic Polynomial time).

**Is ZPP a subset of RP?**

We simply show that ZPP ⊆ RP, and from the fact that ZPP is closed under complement (which can be seen just from switching acceptance and rejection in the definition), we also get that ZPP ⊆ coRP.

**What is a full form of NP?**

abbreviation for nurse practitioner: a nurse who has an advanced qualification and is able to diagnose medical conditions, give treatment, prescribe medicine, etc. Medical treatment: doctors & health workers generally. acupuncturist.

## What is the Fullform of PP?

written abbreviation for pages: used to refer to particular pages in a book or document: see pp 56-58. COMMUNICATIONS UK. written abbreviation for per pro: written in front of a person’s name when you sign a letter or document for them: Yours faithfully, Chris Turner, pp Rebecca Collings.

**What is randomized computation and complexity?**

Probabilistic or randomized computation often provides practical methods to solve certain computational problems. In order to define probabilistic complexity classes we augment Turing machines with an added capability, namely that of flipping (unbiased) coins.

**What is MPP in business?**

Monthly Payment Plan. MPP. Microsoft Partner Program (business solutions; Microsoft, Inc.) MPP. Mass Privatization Program.

### What does MPP stand for marketing?

Market Parity Price (MPP)

**Is RP a subset of BPP?**

Note that both RP and co-RP are subsets of BPP.

**Is BPP a subset of NP?**

The relationship between BPP and NP is unknown: it is not known whether BPP is a subset of NP, NP is a subset of BPP or neither. If NP is contained in BPP, which is considered unlikely since it would imply practical solutions for NP-complete problems, then NP = RP and PH ⊆ BPP.

## Is SAT in Pspace?

SAT is in PSPACE You can solve SAT by trying every possible assignment of values to the variables. That takes a lot of time, but not much space. Think of a truth-value assignment as a sequence of 0’s and 1’s, where 0 indicates false and 1 indicates true. If there are v variables, then there are v bits in the sequence.

**Has anyone solved NP or P?**

Although one-way functions have never been formally proven to exist, most mathematicians believe that they do, and a proof of their existence would be a much stronger statement than P ≠ NP. Thus it is unlikely that natural proofs alone can resolve P = NP.

**What does THX mean in texting?**

### What is a ZPP problem?

Did you actually mean zap or zep? In complexity theory, ZPP is the complexity class of problems for which a probabilistic Turing machine exists with these properties: It always returns the correct YES or NO answer. The running time is polynomial in expectation for every input.

**What is a synonym for complexity?**

Synonyms for complexity complexness, complicacy, complicatedness, complication, elaborateness, intricacy, intricateness, involution, knottiness, sophistication

**What is the difference between Co-RP and ZPP?**

In particular, co-RP is the class of sets for which, if x is not in X, any randomly chosen string is likely to be a witness for non-membership. ZPP is the class of sets for which any random string is likely to be a witness of x in X, or x not in X, which ever the case may be.

## What is the ZPP of the class P?

The class P is contained in ZPP, and some computer scientists have conjectured that P = ZPP, i.e., every Las Vegas algorithm has a deterministic polynomial-time equivalent. There exists an oracle relative to which ZPP = EXPTIME.
