Step (2) Order nonterminals of G´ from X 1 to X n.

Step (1) Find equivalent grammar G´ in CNF.

A → BCDEF becomes: A → BX X → CY Y → DZ Z → EF Conversion into CNF (4) Step 2: Convert production of the form A → B1 B2 … BnĮ.g. Step 1: Convert every production into either: A → B1 B2 … Bn or

Step 2: Substitute more variables in order to make the variable strings shorter.

Step 1: For any production rule with more than one terminal on the right, substitute all with variables.

Every CFG can be rewritten in Chomsky Normal Form.

Step (3) If right-hand side of any production contains three or more nonterminals, then decompose this production into a series of productions the right-hand sides of which consist of exactly two nonterminals.Representatives C a, C b, C c, … and then add new Terminals a, b, c, … in β with new nonterminal → BC nor of form A → a, replace occurrences of Step (2) For remaining production α → β not form A.Step (1) Eliminate ε-productions and unit productions.Is that all Context Free Grammars can be expressed in Chomsky Normal Form? Consider the following simple grammar: Two widely-known forms: Chomsky Normal and Greibach Normalġ Context Sensitive Context Sensitive Linearly Bounded.Having more restricted (but still powerful) grammar forms make important algorithms efficient.Normal forms are special types of context-free languages.Programmers make barely working languages.Of significantly greater accuracy and depth
