Bnf algorithm

BNF is described as a metalanguage for talking about ALGOL by Peter Naur and Saul Rosen. [1] In 1947 Saul Rosen became involved in the activities of the fledgling Association for Computing Machinery , first on the languages committee that became the IAL group and eventually led to ALGOL. See more In computer science, Backus–Naur form or Backus normal form (BNF) is a metasyntax notation for context-free grammars, often used to describe the syntax of languages used in computing, such as computer programming languages See more A BNF specification is a set of derivation rules, written as where: • is a nonterminal (variable) and the See more The idea of describing the structure of language using rewriting rules can be traced back to at least the work of Pāṇini, an ancient Indian Sanskrit grammarian and a revered … See more EBNF There are many variants and extensions of BNF, generally either for the sake of simplicity and succinctness, or to adapt it to a specific application.
