WebStep 1 − Find out nullable non-terminal variables which derive ε. Step 2 − For each production A → a, construct all productions A → x where x is obtained from ‘a’ by removing one or multiple non-terminals from Step 1. Step 3 − Combine the original productions with the result of step 2 and remove ε - productions. Problem WebMay 21, 2024 · Example – Let us take an example to convert CFG to CNF. Consider the given grammar G1: S → ASB A → aAS a ε B → SbS A bb Step 1. As start symbol S appears on the RHS, we will create a new production rule S0->S. Therefore, the grammar will become: S0->S S → ASB A → aAS a ε B → SbS A bb Step 2.
