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.

In Example 6.1, show a derivation tree for the string ababbac, using both the original and the modified grammar. EXAMPLE 6.1 Consider G = ({A, B}, {a, b, c}, A, P) with productions A→a|aaA|abBc,B→abbA|b.A→a|aaA|abBc,B→abbA|b. Using the suggested substitution for the variable B, we get the grammar Ĝ with productions A→a|aaA|ababbAc|abbc,B→abbA|b.A→a|aaA|ababbAc|abbc,B→abbA|b. The new grammar Ĝ is equivalent to G. The string aaabbc has the derivation A ⇒ aaA ⇒ aaabBc ⇒ aaabbc in G, and the corresponding derivation A ⇒ aaA ⇒ aaabbc in Ĝ. Notice that, in this case, the variable B and its associated productions are still in the grammar even though they can no longer play a part in any derivation. We will next show how such unnecessary productions can be removed from a grammar.
Consider the grammar G = ({S, A}, S, {a, b}, P) with the following set of production rules P: S → aS|baA|abaAA → aAbb|aAb|ε 1. Determine what the language generated by G is. You may only use set builder notation and/or language operators in your answer. A proof is not required. 2. Show that the grammar G is ambiguous by: (a) Providing two distinct leftmost derivations for the same string w ∈ L(G).(b) Providing two distinct parse trees for the same string w ∈ L(G).
Let G = ( V, T, S, P ) be the grammar with V = { a, b, c, S }, T = { a, b, c } and the set P of productions S →1 abS, S →2 bcS, S →3 bbS, S →4 a, S →5 cb. Construct derivation trees for the following strings. A. bcbba B. bbbcbba C. bcabbbbbcb

Show the leftmost derivation sequence of the string drdlldrd, (i.e. When deriving a new sentential form, always replace one Nonterminal at a time and always replace the leftmost Nonterminal)3. Suppose d is an abstraction of a command to draw a straight line of fixed length in the current direction, r is an abstraction of a command to turn right by 60 degrees, and l is an abstraction of a command to turn left by 60 degrees. Assuming that you are to start from a point and that the starting direction is to proceed horizontally to the right, show the figure represented by the generated string drdlldrd.4. The string drdlldrdrdrdlldrdlldrdlldrdrdrdlldrd can also be generated.

Question 2-Context-free Grammars Consider the alphabet = {A, V., (,), x, y, z) and the following grammar G = (V,E, R, F), defined by the rules: F (FAF) | (FVF) | (F) | P (a) Identify the set of variables and the set of terminal symbols of G. (b) Identify three words (of lengths between 10 and 20) that can be generated by the above grammar and show their derivations. (c) Consider a modified grammar G', where we remove the brackets '(' and ')' from the alphabet and the derivation rules. That is we set Σ'= {A, V., x, y, z) and we remove all occurrences of brackets in the derivation rules. Show that there are words that are derived ambiguously in G'
