For the parallel SAT solver, a total of 9 qubits are required (three for variable a, two for variables b and c, three for all the clauses, and one for formula \(\mathcal {F}\)). For the distributed SAT solver, a total of 36 qubits are required (9 for formula \(\mathcal {F}\) itself and 27 for performing the proposed distributed quantum protocol).Last Updated: May 5, 2024. The Digital SAT consists of 2 sections, Reading and Writing and Math. Each section is scored on a scale of 200 - 800, and the entire exam is scored on a scale of 400 - 1600, with a 1600 being a perfect score. On the real exam, each question has its own weight, which means that each exam has its own scoring curve.Simple SAT solver for the n-queens problem. Just input the number of queens, voilà!

A SAT solver decides the decision problem of propositional logic (for formulas represented in conjunctive normal form (CNF)). For satisfiable formulas, a SAT solver returns a model, i.e. an assignment that satisfies the formula. For unsatisfiable formulas, most CDCL SAT solvers will return a non-minimal explanation for unsatisfiability.

In logic or computer science, the Boolean Satisfiability Problem (abbreviated as SAT in this assignment) is to determine whether a given propositional logic formulae is true, and to further determine the model which makes the formulae true. The program or tool to answer the SAT problem is called an SAT solver. In this assignment, we'll learn how a …Boolean satisfiability (SAT) solving is a fundamental problem in computer science.
