WebPushdown automata can be described using transition diagrams, as in this example: A transition a; b \to c a;b → c can be followed when the next symbol read from the input string is a a and the symbol popped from the stack is b b. Following this transition causes c c to be pushed onto the stack. Any of the 3 symbols a,b,c a,b,c can be \epsilon ϵ.
