Expert Solution

1) Finite State Machine or finite automata is the automata which accepts regular languages. Finite automata on reading input symbol it moves from one state to another.It is a five tuple Automata.

2) Finite automata with Stack memory is known as Pushdown Automata. It is a six tuple Automata.

3) Unlike the other Automata's Turing Machine has infite length of tap. It is a seven tuple Automata.

4) If the Turing machine is Universal Turing machine, it menas if it solves any problem in given time then it is known as Turing completeness or Turing Universal. The language accepted by this machine is known as Turing complete language.

We demonstrated that if A is recognized by a nondeterministic finite state automaton, it can be recognized by a deterministic finite-state automaton, by giving an algorithm for constructing a machine M' that is deterministic and accepts the same language as a nondeterministic machine M. By the construction algorithm we used, how many states will M' have if M has n states. Justify your answer

DFA Python DFA simulator A deterministic finite automaton (DFA) - also known as deterministic finite state machine - is a finite state machine that accepts/rejects finite strings of symbols and only produces a unique computation (or run) of the automaton for each input string. Write a DFA simulator using the python programming language. Read your DFA from a textfile. First line contains a list of the final states (as integers), separated by a space. Rest of file contains the transitions...

Give the finite-state automaton and the regular grammar for the following: (a) (ab v ba)* v (ab)* (b) (11*)*(110 v 01) (c) All strings over {0,1} containing the string 010 (d) All strings over {0,1} which do not contain the string 010

What is a Turing Machine? Be able to describe its parts. Given a Turing Machine description, be able to carry out a computation and show the resultant tape. What is the halting problem? Is the halting problem decidable? What is Hoare Logic? When proving a program correct, we must look at the initial assertion and final assertion. What are these? What is a loop invariant?

Explain how a Turing Machine can simulate an arbitrary DFA. Use a 2-tape Turing Machine. It can be done with a 1-Tape Turing Machine, but 2-tape will likely make the explanation more intuitive.

prove or disprove A Turing machine with two tapes is no more powerful than a Turing machine with one tape. (That is, both types of machines can compute the same set of functions.) The cardinality of the set of irrational numbers is greater than the cardinality of the set of all rational numbers. The cardinality of the set of all algebraic numbers is exactly the same as the cardinality of all real numbers.

Code the FSM in C++, and show that the program works. Construct a Finite State Machine that models an old-fashioned soda machine that accepts nickels, dimes, and quarters. The soda machine accepts change until 35 cents have been put in. It gives change back for any amount greater than 35 cents. Then the customer can push buttons to receive either a cola, a root beer, or a ginger ale.
