1. Use the algorithm described in our course materials (videos) that takes a CFG and converts it into a CNF grammar that generates the same language as the original grammar, except possibly for the string A, to answer the following question. As part of your answer, you should say which variables are nullable, and you should give the appropriate grammar after each step of the algorithm. There are four steps. Give a CFG (context-free grammar) in CNF (Chomsky Normal Form) that generates the same language, except possibly for the string A, as the following grammar: S → AB A → abA|A B → bBb| bb

Intelligent Machines

Machines that use artificial intelligence to learn from the environment and past experiences to perform better in the presence of variability and uncertainty are called intelligent machines. Intelligence develops according to environment and experience. It is human-like behavior. When the computer system or any programmed machine learns from the inputs and corresponding outputs, it can be called an intelligent machine.

Question

1. Use the algorithm described in our course materials (videos) that takes a
CFG and converts it into a CNF grammar that generates the same language
as the original grammar, except possibly for the string A, to answer the
following question. As part of your answer, you should say which variables
are nullable, and you should give the appropriate grammar after each step of
the algorithm. There are four steps.
