Informally, it says that all sufficiently long words in a regular language may be pumped—that is, have a middle section of the word repeated an arbitrary number of 

The Pumping Lemma (Machine Version 1.0) For any deterministic machine M, for all w ∈ L(M) of length greater than or equal to the number of states in M, there 

Q: Why do we care about the Pumping Lemma` A: We use it to prove that a language is NOT regular. Q: How do we do that? A: We assume that the language IS REGULAR, and then prove a contradiction. Q: Okay, where does the PL … This video is the code behind the pumping lemma for the language (L) and explanation Below is the Source Code to test and see how the exercise truly works yourself!

Now, when applying the pumping lemma you can restrict yourself to any word $w\in L$ that is convenient to you, as long as $|w|\geq p$. Since you can do that, I would go for even simpler words, like $w=a^pba^p$. $\endgroup$ – plop Mar 1 at 17:35 To prove {aibjck | 0 ≤ i ≤ j ≤ k} is not context free using the Pumping Lemma • Suppose {aibjck | 0 ≤ i ≤ j ≤ k} is context free. • 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 1996-02-18 That is easily doable by the separate pumping lemma for linear languages (as given in Linz's book), but my question is different.

So, first of all we need to know when a language is called regular. A language is called regular if: Language is accepted by finite automata. A regular grammar can be constructed to exactly generate the strings in a language.

Pumping Lemma (for Regular Languages) If A is a Regular Language, then there is a number p (the pumping length) where if s is any string in A of length at least p, then s may be divided into 3 pieces, s = xyz, satisfying the following conditions: a. For each i ≥ 0, xy iz ∈ A, b. |y| > 0, and c. |xy| ≤ p.
