Get rid of all productions. Web in greibach normal form. Web the conversion to chomsky normal form has four main steps: , where s is the starting variable;. Make the rhs consist only of variables. Assume that g is in chomsky normal form • let v =. Web we will put these rules in the right form by applying the following two transformations: Let g = (v,σ,r,s) be a cfg generating l. Web in the chomsky normal form (cnf), only three types of rules are allowed: Get rid of all productions. Rules of the type s !
