Give a six-state (including dead state) DFA for the language {w ∈ {a,b}*: w contains abb as a substring, and does not contain bba}
We need minimum seven-states to construct DFA for given language including dead state.
Thank you.

Construct a DFA for the simpler language, then use it to give the state diagram of a DFA for the language given. In all parts, Σ = {0, 1} {w|w is any string not in 0*1*}
Question 1: Design a DFA with at most 5 states for the language L1 = {w ∈ {0, 1}∗ | w contains at most one 1 and |w| is odd}. Provide a state diagram for your DFA. Approaching the Solution --since we haven’t really practiced this type of assignment (i.e. had to define our machine based on only having the language given; not the formal 5 tuples), I am providing the steps for how to work through this; you are...
1. Construct a DFA that recognizes each of the following languages: a. L1 = {w € {a, b}* | w contains at least two a's and at least two b’s} b. L2 = {w € {a,b}* | w does not contain the substring abba} C. L3 = {w € {a, b}* | the length of w is a multiple of 4}
Give cfg for the following language over {0,1} {w | w contains the substring 011}
Create a DFA for the language L = {w ∈ {0, 1}∗ : w is a set of strings with 011 as a substring AND is not divisible by 3 }. First, create two separate DFAs for is a set of strings with 011 as a substring and not divisible by 3. Then, create the intersection between those DFAs by using the product construction. Show all your work. Hint: Use the least amount of states as possible.
I need to construct a deterministic finite automata, DFA M, such that language of M, L(M), is the set of all strings over the alphabet {a,b} in which every substring of length four has at least one b. Note: every substring with length less than four is in this language. For example, aba is in L(M) because there are no substrings of at least 4 so every substring of at least 4 contains at least one b. abaaab is in...
Consider the language denoted by a U ab. The alphabet is {a,b}. (a) Design a DFA for the above language. (b) Show that any DFA for the above language has to have at least 3 accepting states and one dead state.
please I need it urgent thanks. subject programming language and compilers w does not contain Question 2 Consider the following language over the alphabet = {a,b}: L = {w the substring aa} 1. What is I, the complement of L? 2. Write a regular expression for L. 3. Write a regular expression for L. 4. Design a DFA for I. 5. Modify the DFA for I to make it a DFA for L.
Question 1. Let Σ = {a, b}, and consider the language L = {w ∈ Σ ∗ : w contains at least one b and an even number of a’s}. Draw a graph representing a DFA (not NFA) that accepts this language. Question 2. Let L be the language given below. L = {a n b 2n : n ≥ 0} = {λ, abb, aabbbb, aaabbbbbb, . . .} Find production rules for a grammar that generates L.
1. (a) Give state diagrams of DFA’s recognizing the following languages. That alphabet is Σ = {a,b} L1 = {w | w any string that does not contain the substring aab} L2 = {w | w ∈ A where A = Σ*− {a, aa, b}} 2. (a) Give state diagrams of DFA’s recognizing the following languages. The alphabet is {0, 1}. L3 = {w | w begins with 0 ends with 1} (b) Write the formal definition of the DFA...
