Let's consider a grammar for expressions is defined as follows. -> = -> A | B | C | D -> +                 | *                 | ( )                 | 1. Is this grammar unambiguous? Can you explain in detail? 2. How can I design a PDA (PushDown Automata) M that recognizes the BNF (i.e. a metasyntax notation for CFG)?

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.
