L 87 Steps in Converting Context free grammar to Chomsky Normal Form
Get rid of all productions. Web chomsky normal form enables a polynomial time algorithm to decide whether a string can be generated by a grammar. Get rid of all productions where rhs is onevariable. 1 i your first grammar, you can derive epsilon from s. If the start symbol s occurs on the right side of a grammar. Rules of the type s !, where s is the starting variable; Every cfl can be generated by some grammar in chomsky normal form. Web steps for converting cfg into cnf. Therefore you must have a epsilon in the second. Eliminate start symbol from the rhs.
Web chomsky normal form enables a polynomial time algorithm to decide whether a string can be generated by a grammar. Get rid of all productions. Therefore you must have a epsilon in the second. Get rid of all productions where rhs is onevariable. Web what is chomsky normal form. Web to begin conversion to chomsky normal form (using definition (1) provided by the wikipedia page), you need to find an equivalent essentially. Eliminate start symbol from the rhs. A!bcfor some b;c2vwith b;c6= s, a!afor some a2 , or s! The algorithm is pretty slick if you. If the start symbol s occurs on the right side of a grammar. So the empty word belong to the described language.
