Answer :

This is accurate because there are an uncountably infinite number of descriptions of context-free languages, each of which has a finite length.

Explain about context-free?

  • Considering the available options, the statement that is considered wrong is "Context-sensitive language is a subset of context-free language."
  • This is because generally every regular language can be produced through the means of context-free grammar, while context-free language can be produced through the means of context-sensitive grammar, and at the same time, context-sensitive grammars are produced through the means of Recursively innumerable.
  • Hence, the correct answer in this correct answer to the question is the last option *Context-sensitive language is a subset of context-free language.

a . Regular language -

Uses are as follows -

  1. Matching the regular expression patterns , like the Unix grep  .
  2. Patterns search and replace operations .
  3. Programming languages for the Lexical analysis in the compilation phase b. Context Free Language -

Uses are as follows -

  1. Match the count of one symbol with another symbol  .
  2. Match a symbol with another symbol  .
  3. Submit one symbol with string made of other symbols recursively .

c. NP-Completeness  -

Uses are as follows -

  1. used for Weighted Model Counting
  2. Used for Integer Programming
  3. used for Boolean Satisfiability testing

d. Decidability -

Uses are as follows -

  1. Team games with incomplete information are undecidable.
  2. Infinite chess (with limitations on rules and game pieces) is decidable.
  3. Chess is decidable game
