1 i your first grammar, you can derive epsilon from s. Every cfl can be generated by some grammar in chomsky normal form. Replace every production that is too. What is the chomsky normal form for the following cfg? Web what is chomsky normal form. Get rid of all productions. Rules of the type s !, where s is the starting variable; The algorithm is pretty slick if you. Web to begin conversion to chomsky normal form (using definition (1) provided by the wikipedia page), you need to find an equivalent essentially. Web only if all rules are of the form:
Web 1 answer sorted by: Web chomsky normal form step 1 add new start variable step 2 remove all ε rules step 3 remove all unit rules step 4 standard form conversion Rules of the type s !, where s is the starting variable; 1 i your first grammar, you can derive epsilon from s. Therefore you must have a epsilon in the second. 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. Web chomsky normal form enables a polynomial time algorithm to decide whether a string can be generated by a grammar. Web only if all rules are of the form: Web the conversion to chomsky normal form hasfour main steps:
