Pumping lemma. It is used to prove that a language is not regular. It cannot used to prove that a language is regular. If A is a regular language then A has a pumping length P such that any string S where |s|>=P may be divided into three parts S=xyz such that the following conditions must be true :
The proofs of these lemmas typically require counting arguments such as the pigeonhole principle. The two most important examples are the pumping lemma for

Pumping Lemma is used as a proof for irregularity of a language. Thus, if a language is regular, it always satisfies pumping lemma. If there exists at least one string made from pumping which is not in L, then L is surely not regular. The opposite of this may not always be true.
These regular expressions, however, do not themselves form a regular language, as can be seen using the pumping lemma. On the other hand

The pumping lemma establishes a method by which you can pick a "word" from the language, and then apply some changes to it. The theorem
Page 8. The Pumping Pumping Lemma in Plain English. ✦ Let L be a regular language and let p = “ pumping length” = no. of states of a DFA accepting L. ✦ Then, any string s in L of Aug 18, 2013 After everyone understood the point of the pumping lemma, you write it down formally using five quantifiers, so that student can write it down Pumping Lemma for Regular Languages: Surhone, Lambert M.: Amazon.se: Books.
• Let s = apbpcp • The pumping lemma says that for some split s = uvxyz all the following conditions hold • uvvxyyz ∈ A • |vy| > 0 Case 1: both v and y contain at most one type of symbol

That is easily doable by the separate pumping lemma for linear languages (as given in Linz's book), but my question is different. Evidently this is a CFL, and a pushdown automaton can be constructed for it. The pumping lemma is often used to prove that a language is: a) Context free b) Not context free c) Regular d) None of the mentioned SOLUTION Answer: b Explanation: The pumping lemma is often used to prove that a given language L is non-context-free, by showing that arbitrarily long strings s …
Why the pumping lemma is as it is, it's probably just cultural and somewhat arbitrary. $^1$ there actually exists an infinitude of DFAs that recognize it, as you can always add unreachable dummy states. However, things get simpler if we choose to only be interested in the minimal DFA - the one with the smallest number of states.
