Can you describe an algorithm that given two context-free grammars G1 and G2 outputs YES if and only if every string generated by G1 is also generated by G2. (I.e., output YES exactly when the set of strings generated by G1 is a subset of the set of strings generated by G2.)

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.
