5. Consider the heuristics for this problem shown in the table above, h1 is admissible. This table provides a comparison of heuristic values for different states labeled from S to G. The two columns, h1 and h2, represent different heuristic evaluations for each state.- **State S:** - h1: 3 - h2: 3- **State A:** - h1: 3 - h2: 2- **State B:** - h1: 5 - h2: 5- **State C:** - h1: 2 - h2: 1- **State D:** - h1: 3 - h2: 2- **State E:** - h1: 4 - h2: 4- **State G:** - h1: 1 - h2: 0This information is useful in understanding how different heuristic functions evaluate various states in a search problem.

An admissible heuristic must underestimate or be equal to the true cost.A consistent heuristic must…

I'm having a difficult time with this problem. Could you lend me a hand in understanding it? I'd appreciate a step-by-step explanation, along with insights into how you arrived at the solution. here is the question I need help with:4.3 Let ALLDFA = {<A> | A is a DFA and L(A) = Σ∗ }. Show that ALLDFA is decidable
Exercise c. Ask the oracle. (Textbook problem 4.1) Suppose that we have access to an oracle who can answer the decision problem CNF-SAT. Show that, by asking her a polynomial number of questions, we can find a satisfying assignment if one exists. Hint: first describe how setting a variable gives a smaller CNF-SAT formula on the remaining variables. An "oracle" is a subroutine you can call that answers the question (in this case, whether the given CNF formula is satisfiable), but that costs no time to call.
3. Express the following English sentences using propositional functions, quantifiers and logical connections. (a) Someone in the class is helped by everyone in the class. (b) There is a hard working student in the class who has not been helped by any student in class. (c) For everyone in the class, someone who is smart has helped him/her. SO (d) There are two people in the class who have not helped each other. (e) There is a hard working student in the class who is helped by every smart student in class. (f) There are some companies that hire only hard working students.

Question 1 Consider the following model of the quantified relational logic of a hypothetical love triangle. U = {Alice, Bob, Carol, Dominic} a=Alice,b=Bob,c=Carol,d=Dominic [L] = {< Alice, Alice >, < Bob, Bob >, < Dominic, Dominic >, < Alice, Dominic >, < Dominic, Carol >, < Carol, Alice >, < Alice, Carol >, < Bob, Alice >, < Bob, Dominic >} Determine which of the following sentences are true in the model. You may read the formula Lxy as “x loves y”. If an existential sentence is true, provide at least one witness. If a universal sentence is false, provide at least one counterexample.
