10 points (bonus) A propositional formula on n variables, P(ri,2,... ,Tn) is satisfiable if there exists an assignment of truth values (true or false) to its variables such that it evaluates to true. (a) Give an algorithm (pseudocode) that, given a formula P determines if it is satisfiable or not. Analyze your algorithm. b) Suppose that we are given a free" algorithm A that, given P and a partial assignment of truth values (that is, some variables are set to...
Check is 2-CNF satisfiable? Return one of its satisfying assignments.
The input is a Boolean formula in 2-CNF, given as a string of symbols.Example: p /\ (p -> q) /\ (p -> ~r) /\ (~r \/ ~s) /\ (s \/ ~q)1) check whether the given 2-CNF is satisfiable.2) given a 2-CNF, report that it is not satisfiable or return one of its satisfying assignments.Solution in Python3For the first task, you should implement a function called is_satisfiable, which takes the string with the 2-CNF as an argument and returns either True (satisfiable) or False (not satisfiable). The second task...

Suppose that we add a new quantifier called exists unique to first- (d) order logic, using the symbol 3! to represent it. It means that there is exactly one element of the universe that satisfies the subsequent formula. In this question, variables will range over the universe of numbers. [1 mark] (0) Is 3!x. x + x 2 valid? Why? Give an example of a valid formula that uses the quantifier, and an example of an unsatisfiable one. Both must...
