Objectives

Objectives of this assignment are to make students able to understand the following concepts,
  • Transition Graph
  • Regular Languages
  • Non-Regular Languages
  • Pumping Lemma Version I
  • Pumping Lemma Version II

Assignment No.4


Question No 1
Marks: (2.5*4) =10 
Recall the idea of regular languages, so if L1 and L2 are regular languages then L1 + L2 , L1L2 and L1* are also regular languages. If L1 and L2 are expressed by TG1 and TG2 given below then find:
  1.        I.      L1 + L2
  2.     II.      L1L2
  3.  III.      L1*
  4.   IV.      L2

L1= {all words that have different first and last letters}
L2= {Λ, ab, aaa, bbbb}




Question No 2
Marks: (5*2) =10
Suppose we have a language defined below:
à anb3n Where n = 1, 2, 3 …
Some strings belonging to this language are, abbb , aabbbbbb , aaabbbbbbbbb, …..
à [a1b3, a2b6 ,a3b9 ,a4b12, …]
Using below given methods, prove that the given language is non-regular:
  1. Pumping Lemma Version I
  2. Pumping Lemma Version II

Hint: [Make use of some example strings]
