Can anyone help me transform the following G to Chomsky Normal Form?
S --> abAB
A --> bAB | λ
B --> BAa | A | λ
Thanks for your help!

The purpose of transforming a grammar to Chomsky Normal Form is to make it easier to analyze and generate the language it describes. This form has specific rules and restrictions that allow for more efficient parsing algorithms to be used, making the grammar more manageable for computers to process.
The steps involved in transforming a grammar to Chomsky Normal Form include removing all ε-productions, removing all unit productions, converting all productions to either A → BC or A → a form, and finally, introducing new non-terminals for each terminal in the grammar. This process may also require the addition of new start and end symbols.
Yes, any context-free grammar can be transformed to Chomsky Normal Form. However, some grammars may require more complex transformations or the addition of new symbols to meet the necessary rules and restrictions.
The language described by a grammar is not affected by transforming it to Chomsky Normal Form. The transformation only changes the structure of the grammar and makes it easier to analyze and process.
One potential disadvantage of transforming a grammar to Chomsky Normal Form is that it may result in a larger grammar, as new non-terminals and productions may need to be added. This could make the grammar more complex and difficult for humans to understand. Additionally, the transformation process itself can be time-consuming and may require manual adjustments in some cases.
