Satisfiability Problem: The problem to determine if there exists an interpretation that would satify a given boolean formula is known a satisfiability problem. In a given Boolean formula it is asked whether it’s variables could be replaced by values “TRUE” or “FALSE” such that formula evaluates to “TRUE”. In such a case, the boolean formula is called satisfiable. Otherwise, if there is no such assignment possible and the function becomes “FALSE” for all variable assignments possible, then the formula is unsatisfiable. 3-Satisfiablity: The satisfiability of a formula stated in a conjunctive normal (CNF) form is been determined where each clause is been limited to atmost three literals, such a problem is termed as 3-satisfiability problem.

Satisfiability Problem:

The problem to determine if there exists an interpretation that would satify a given boolean formula is known a satisfiability problem.

In a given Boolean formula it is asked whether it’s variables could be replaced by values “TRUE” or “FALSE” such that formula evaluates to “TRUE”.

In such a case, the boolean formula is called satisfiable.

Otherwise, if there is no such assignment possible and the function becomes “FALSE” for all variable assignments possible, then the formula is unsatisfiable.

3-Satisfiablity:

The satisfiability of a formula stated in a conjunctive normal (CNF) form is been determined where each clause is been limited to atmost three literals, such a problem is termed as 3-satisfiability problem.

Explanation of Solution

Boolean expression with one variables:

Consider an instance when an alternative in a Boolean expression has two variables.

A = q1

Convert the above satisfiablity problem into 3-satisfiability problem by generating the below expression. Transform each clause into a conjunction of “n-2” clauses, where “n” denotes the total count of literals in all clauses.

A' = (q1∨x∨y)((q1∨¬x∨y)∧(

Homework You have the row vector (A) that has values from (-100 to 100), write MATLAB codes to: (1) Interchange the first 10 elements with last ten elements. (2) Replace the elements at indices (93,9,17,50) of A with 99. (3) Return the second element and the element before the last of A as a column vector (C1). (4) Extract the first five elements and the last five elements of A and append them as a row vector (R). (5) Set the elements of A with odd indices to zeros(0).
