Q. The formal description of a NFA (Nondeterministic finite automaton) is: ({q1, q2}, {0,1}, 6, q1, {q2}), where & is given by the table: 1 {q1} {q1} {q1, 92} qi Ø q2 {q2} {q1} Please Convert given Nondeterministic finite automaton (NFA) to Deterministic finite automaton (DFA) for L, where L is the language recognized by NFA. Show work.
Racket code only please Using the logical operators, and, or, implies, not, and iff, and atoms representing truth values, we can make a list that would represent proposition: For instance: '(A and (not A)), or '((B iff (A or C)) implies (not (C implies A))) would represent the formal statements (A∧¬A) and ((B ≡(A∨C)→¬(C → A))). We use the following convention when we represent propositions in this way: for every operator – unary or binary – there corresponds at least one pair of parentheses defining its scope (and perhaps more). Thus, the lists ‘(A and not A) and (B iff A or C) are not permitted but ‘((A and ((not A))) and ‘(B iff (((A or C)))) are acceptable. 1. Define collect-prop-variables, which will take as input a list representing a proposition, and return a list, representing a set, of all the variables used in the expression. Example: (collect-prop-variables '(A and (not A))) should return '(A) and (collect-prop-variables '((B iff (A or C)) implies (not (C implies A))) )…

Define Evaluate-WFF, which will take as input a formula of prepositional logic in which there are only truth values and no propositional variables, such as the following: (#t or (not #t)). Evaluate-WFF should return #t if the formula under the particular truth assignment evaluates to #t and false otherwise. By way of example,…

2. Consider the following information: - Animals can outrun any animals that they can eat. Carnivores eat other animals. - Outrunning is transitive: if x can outrun y and y can outrun z, then x can outrun z. Lions eat zebras. Zebras can outrun dogs. Dogs are carnivores. Using this a. Write a set of FOL sentences representing the information using the standard notation for FOL. b. Convert these sentences to clausal normal form. c. Use resolution theorem proving to find three animals that lions can outrun, showing the result as a proof graph.
Each sentence should be matched by the correct answer in the list.
