    5-minute concise explanations are so much better than lectures that are over an hour long. Much easier to remember :)

    when u take 3 cases, in those last 2 cases, you are taking y such that |xy| is already greater than p. You basically need to chose a y such that |y| is greater than 1 and less than p and |xy| must be less than p.

    In regular language we can make state diagram, so we know,
    number of states=p
    but in non-regular language we cannot make state diagram for language.
    then how we are going to find p for non-regular language?

    • @i3aluchi
      @i3aluchi 3 роки тому

      To my humble knowledge, we don't necessarily choose P as the number of states as it is dependant on the language and not the machine.

  • @mangilalkaler3497
    @mangilalkaler3497 3 роки тому

    At 4:30, I assume you wanted to say : Assume the language is regular. Then given P, we find a string that can't, in fact, be pumped and still be in the language. This proves the language is non-regular, which contradicts our initial assumption.

    Hi I had a question regarding the 3 cases for the pumping lemma. If we could prove one of the cases was true for the y value chosen, and it met all the three conditions for pumping lemma, then that would show the language is regular then, correct?

  • @carpedm9846
    @carpedm9846 3 роки тому

    Couldnt you have chosen a pair of 01, and thus keep the sequence?

    • @iliasvrynas9189
      @iliasvrynas9189 3 роки тому

      Yes but I think you need to find at least one sequence that is not part of the language

    • @cirosilvano6950
      @cirosilvano6950 2 роки тому

      The language you’re talking about is different though. She was proving that the language consisting of an uninterrupted sequence of n 0s followed by an uninterrupted sequences of n 1s is irregular.
      Strings in such format correspond to stuff like 000111, 01, 00000001111111 and so on, while 01010101, for example, doesn’t belong to such language.
