## List of important Push Down Automata (PDA) – Homepage

Here we have a list of important Push Down Automata (PDA) used in the theory of automata and theory of computation.

1 | PDA for b twice |

2 | PDA for unequal a’s and b’s |

3 | PDA for four variables |

4 | PDA for Regular Languages |

5 | PDA for the language of a^{n}b^{n}c^{2n} |

6 | PDA for a^{m}b^{n}a^{n}b^{m} in theory of automata |
