In computer science and formal methods, a SAT solver is a computer program which aims to solve the Boolean satisfiability problem (SAT). 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 ...
At this time, the SAT was standardized so that a test score received by a student in one year could be directly compared to a score received by a student in another year. Test scores ranged from 200 to 800 on each of two test sections (verbal and math) and the same reference group of students was used to standardize the SAT until 1995. [230]
The scaled score was the only score reported to either students or colleges, and ranged from 200 to 800, with 800 being the best possible score. The standard deviation between test scores in 2006 was 102. [2] Less than one percent of the 2006 College-Bound Seniors taking the test received a perfect score of 800. None got a score lower than 260.
The test developers, using test score data from 1926 and 1927 to calculate correlations between the various SAT sub-tests, felt that the mathematics sections were measuring a different component of intelligence than the verbal sections, and should be removed to be re-developed later as sub-tests with a score separate from that of the verbal ...

The conversion between these numbers varied depending on the difficulty of a particular test administration. The scaled score was the only score reported to either students or colleges, and ranged from 200 to 800, with 800 being the best possible score. The standard deviation of the test scores in 2006 was 105. [10] 15 percent of the 2012 ...
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 ...
All questions had five answer choices. Students received 1 point for every correct answer, lost ¼ of a point for each incorrect answer, and received 0 points for questions left blank. This score was then converted to a scaled score of 200–800. The mean score for the 2006–07 test administrations was 643 with a standard deviation of 107.
