In computer science and formal methods, a SAT solver is a computer program which aims to solve the Boolean satisfiability problem.On input a formula over Boolean variables, such as "(x or y) and (x or not y)", a SAT solver outputs whether the formula is satisfiable, meaning that there are possible values of x and y which make the formula true, or unsatisfiable, meaning that there are no such ...
An examination book, or exam book, or Blue book is a notebook used by students of many post-secondary schools in the United States to write essays and answer multiple short-answer questions when their assessment tests are administered. The books commonly have blue cover and are titled "Blue book", although books called simply "Examination book ...
A blue book exam is a type of test administered at many post-secondary schools in the United States. Blue book exams typically include one or more essays or short-answer questions. Sometimes the instructor will provide students with a list of possible essay topics prior to the test itself and will then choose one or let the student choose from ...
A variant of the 3-satisfiability problem is the one-in-three 3-SAT (also known variously as 1-in-3-SAT and exactly-1 3-SAT). Given a conjunctive normal form with three literals per clause, the problem is to determine whether there exists a truth assignment to the variables so that each clause has exactly one TRUE literal (and thus exactly two ...
He constructs a PCP Verifier for 3-SAT that reads only 3 bits from the Proof. For every ε > 0, there is a PCP-verifier M for 3-SAT that reads a random string r of length ( ()) and computes query positions i r, j r, k r in the proof π and a bit b r. It accepts if and only if 'π(i r) ⊕ π(j r) ⊕ π(k r) = b r.
The Stanford Achievement Test Series, the most recent version of which is usually referred to simply as the "Stanford 10" or SAT-10, is a set of standardized achievement tests used by school districts in the United States and in American schools abroad for assessing children from kindergarten through high school.

Schools also varied with regard to their SAT Subject Test requirements of students submitting scores for the ACT in place of the SAT: some schools considered the ACT an alternative to both the SAT and some SAT Subject Tests, whereas others accepted the ACT but required SAT Subject Tests as well. Information about a school's specific test ...
Partial Max-SAT can be solved by first considering all of the hard clauses and solving them as an instance of SAT. The total maximum (or minimum) weight of the soft clauses can be evaluated given the variable assignment necessary to satisfy the hard clauses and trying to optimize the free variables (the variables that the satisfaction of the ...
