(proof by simula-tion) Each step of the derivation is a string. The ma-chine guesses the next step. The problem is to do this with only a stack. Terminals to the left of leftmost variable are not WebAnother way of writing that is you can say, u goes to v if there are a bunch of one-step moves that you can make which take you from u to v. And that whole sequence is called a derivation of v from u. That's a sequence of steps that you go through doing these substitutions one by one to take you from u to v, according to the rules of the grammar. porch light bulb fema trailer
