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

The image presents an exercise to fill in the blanks with proper words related to formal language theory and automata. Here is the transcription with the blanks left open:

---

(2) Fill the proper words in the blanks:

(i) A language is regular ______ it can be accepted by a DFA. A language is context-free if and only if it can be accepted by ______.

(ii) Let \( G = (V, T, S, P) \) be a context-free grammar. Given any string \( w \), \( w \) belongs to \( L(G) \) ______ there exists a derivation tree of \( G \) whose yield is \( w \).

(iii) Suppose that \( G = (V, T, S, P) \) is a context-free grammar. If \( G \) doesn't have any rules of the form \( A \rightarrow \lambda \) and \( A \rightarrow B \), where \( A \) and \( B \) are the variables in \( V \), then the exhaustive search parsing method can be made into an algorithm which can determine if \( w \) belongs to \( L(G) \) or not in no more than ______ rounds.
