  1. pumping lemma: ww^R not regular - Mathematics Stack Exchange

    I'm trying to prove that $L = \ {ww^R : w \in \ {a,b\}^*\}$ ($w^R$ is the reverse of $w$) is not regular using the pumping lemma. Let $p$ be the pumping length and $s ...

  2. Context free grammar: Meaning of notation ww^R

    Aug 22, 2017 · A common example in CFG is the palindrome example. These examples often contain the $\\ ww^R$ notation for the string. An example from my class could be: Strings $\\ …

    This question would have been perfect for the upcoming Computer Science Stack Exchange. So, if you like to have a place for questions like this one, please go ahead and help this proposal …

  4. formal languages - Build a deterministic turing machine to decide …

    Sep 6, 2024 · Are you interested in finding a determistic algorithm to solve the problem? Or do you really need to know a Turing machine specification, with states and transition functions …

  5. formal languages - Pumping lemma, L= {WW^R | W can be {1 ...

    Feb 5, 2019 · im trying to find out, if L is regular or not using pumping lemma. I have L={WW^R | W can be {1}+} So possible strings would be 11, 1111, 111111. In every cases i have googled …
