ANNSWER BY TRUE OF FULSE: (No need to explain as I already know the answer but I want to check my answers. i. For every regular language, G, there exists a push down automata, M such that L(G)=L(M).    ii.The following grammar represents the language of all strings over the alphabet a and b, with the total number of a’s being equal to the number of b’s S → aSb | aabb  iii. The following languages MUST at least be defined by Pushdown Automata L = {ab, abab, ababab, abababab, ...}.  iv. The correct CFG for the language L = (aa + bb)* is S → aB | bA | λ; A → aS; B → bS

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.
