title: Regex is for Regular Grammars as to ____ is for Context Free Grammars
body: <p>I have just learned that <code>Regular Grammars</code> have their corresponding <code>Finite State Acceptors</code> which will correspond to <code>Regular Expressions</code>.</p>
  
  <p>Is there an equivalent conversion with <code>Context Free Grammars</code>? As far as I know Context Free Grammars can be represented by <code>Push Down Automata</code> which in turn would correspond to what?</p>
  
  <p>Thanks to anyone who would clear my mind off of this.</p>
