WebSteps for converting CFG into CNF. Step 1: Eliminate start symbol from the RHS. If the start symbol T is at the right-hand side of any production, create a new production as: S1 ā†’ S. Where S1 is the new start symbol. Step 2: In the grammar, remove the null, unit and useless productions. You can refer to the Simplification of CFG. WebFormal definition of Turing machine.
