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...

4. The NOT-ALL-EQUAL 3SAT problem is defined as follows: Given a 3-CNF formula F, is there a truth assignment for the variables such that each clause has at least one true literal and at least one false literal? The NOT-ALL-EQUAL 3SAT problem is NP-complete. This question is about trying to reduce the NOT-ALL-EQUAL 3SAT problem to the MAX-CUT problem defined below to show the latter to be NP-complete. A cut in an undirected graph G=(V.E) is a partitioning of the...

C++ 1st) [Note: This assignment is adapted from programming project #7 in Savitch, Chapter 10, p.616.] Write a rational number class. Recall that a rational number is a ratio-nal number, composed of two integers with division indicated. The division is not carried out, it is only indicated, as in 1/2, 2/3, 15/32. You should represent rational numbers using two int values, numerator and denominator. A principle of abstract data type construction is that constructors must be present to create objects...
