Convert the following DFA into a regular expression by computing all Rij (k) regular expressions: 0...
a. Draw the transition diagram for the DFA
b. Construct a regular expression for the language of the DFA
by computing all the R_ij^(k) regular expressions.
Consider the following DFA: 1 A В C B A C В
Convert the following DFA to a regular expression. Dead state and transitions to it not shown, but remember that the dead state has no outgoing transitions. [6]
1. Construct a DFA for each of the following regular expressions: a) ab + c b) a*b + c c) ab*c*+ ac 2. Construct an NFA for the following regular expression: a) (a + b)*ab b) a*b* c) a*b* + c d) a* + b* e) a* + b* + ac*
1.Calculate a regular expression corresponding to the following
DFA, available at the jflap.org website, by the method of solving a
system of simultaneous equations in standard form. q0 is indicated
as the initial state.
2.Convert your regular expression to an NFA using the procedure
of Hopcroft and Ullman
3.Convert the NFA - to a DFA.

1. Write regular expressions to capture the following regular languages: (a) The set of binary strings which have a 1 in every even position. (Note: odd positions may be either 0 or 1.) (b) The set of binary strings that do not contain 011 as a substring. (c) Comments in Pascal. These are delimited by (* and *) or by { and }, and can contain anything in between; they are NOT allowed to nest, however. 2. Write a DFA...
Using formulas for r_i, j^k find a regular expression for the following dfa: Determine a right-linear grammar G for the language accepted by the following dfa: Find the dfa that accepts the intersection of languages accepted by dfas from problem 1 and problem 3. Use the construction based on pairs of states.
Converting a DFA such as the one below to a regular expression requires 0/1 us to develop regular expressions for limited sets of paths --- those that take the automaton from one particular state to another particular state, without passing through some set of states. For the automaton below, determine the languages for the following limitations: 1.LAA = the set of path labels that go from A to A without passing through C or D. 2. LAB = the set...
6. (a) Use Thompson's construction to convert the above regular expression 1(0/1) *101 into an NFA (7 points) (b) Convert the NFA of part (&) into a DFA using the subset construction (points)
