Task Background: Automata theory involves the study of mathematical objects called automata and the computational problems that can be solved using them. Context-free grammar provides us with mathematical techniques of building phases in a language from other blocks that are smaller. Visual structures called parse trees enable us to clearly differentiate which phrases are unique and which ones are ambiguous.

Primary Response: Within the discussion board area, respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your fellow classmates. Be substantive and clear.

Task Assignment: Below you will find a question the areas of automata. Solve the problem showing all steps. Thoroughly explain how and why you performed each step with complete sentences.

A finite-state automaton is given by the 5-tuple (Q, ∑, δ, q, F), where

Q = the finite set of states = {A, B, C}

∑ = the Alphabet (inputs) = {x, y}

δ = the transition function using the alphabet as inputs to the states

q = the initial state = {A}

F = Accepting (or final) state = {C}

The transition table for the automaton is given by:

 δ δ x y A A B B A C C A C

(i). Draw the corresponding transition diagram (digraph).

(ii). Provide 5 strings that are in the language generated by the automaton.

(iii). Provide 5 strings, that use the same inputs, which are not in the language generated by the automata.

(iv). Write a general statement that describes when a string is part of the language generated by the above automata and when that string is not in the language.
