Following is the NFA which will accept the strings over {a, b, c} that are in alphabetical order.
Accepted strings:
{a, b, c, aa, ab, bc, abc, aabc............}
All three states are final states.
For help please comment.
Thank You.
2. Construct a NFA for the language over Σ-{a,b,c} that contains all words whose symbols are in alphabetical order....
Let Σ = {a, b}. Consider the language L over Σ that contains Λ and all words whose length is divisible by 6. Build a transition graph that accepts L.
Languages to NFA / ε-NFA A) Make an ε-NFA (An Epsilon NFA) for the language L3 = L1L2. Where: L1 = all strings over Σ= {0,1} that end in…001 and L2 = all strings over Σ= {0,1} that contain 010 anywhere in the string...(beginning, middle or end) B) Convert the ε-NFA (Epsilon NFA) from Part A into a regular NFA. C) Convert the NFA From Part B into a DFA.
Part A) Construct an NFA (non-deterministic finite automata) for
the following language.
Part B) Convert the NFA from the part A into a DFA
L- E a, b | 3y, z such that yz, y has an odd number of 'b' symbols, and z begins with the string 'aa') (Examples of strings in the language: x = babbaa, and x = abaabbaa. However, x-bbaababaa is not in the language.)
L- E a, b | 3y, z such that yz, y...
2. a. Draw a NFA that accepts all strings over Σ = {?, ?} that either end in ?? or contain the substring ??. b. Then convert the NFA in the previous exercise to a DFA
1. Construct a Finite Automata over Σ={0,1} that recognizes the language {w | w ∈ {0,1}* contains a number of 0s divisible by four and exactly three 1s} 2. Construct a Finite Automata that recognizes telephone numbers from strings in the alphabet Σ={1,2,3,4,5,6,7,8,9, ,-,(,),*,#,}. Allow the 1 and area code prefixing a phone number to be optional. Allow for the segments of a number to be separated by spaces (denote with a _ character), no separation, or – symbols.
9. Construct minimal NFA that all accepts all strings of {a,b} which contains atmost 2 a’s.
4. Construct a grammar over {a, b} whose language is {a"b"|0sn<m<3n}.
3. Construct minimal NFA that all accepts all strings of {a,b} which contains aa or bb as substring.
2. (a) Using Thompson's construction, construct an NFA that recognizes the same language as defined by the following regular expression (1 010) *1 (b) Using the subset construction, convert the NFA into a DFA. Optimize the resulting DFA by merging any equivalent states
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.
