One of the key examples of an NP problem is the satisfiability problem: NP问题的一个关键例子是可满足性问题: SAT:Given an expression in n boolean variables, is there an assignment of the variables such that the expression evaluates to True? SAT:给定一个在n个布尔变量中的表达式,是否存在变量赋...
另外大家或许留意到,如果我们变换寄存器的位置,会影响到部分控制逻辑(状态机)的,所以其实有一些约束条件的,这些约束条件大多可以转化为SAT问题(布尔可满足性问题,Boolean Satisfiability Problem)并且利用SAT专用求解器求解。此外综合过程中对时序的优化还包括状态最少化、同步异步电路优化、死状态检测/消除、时钟漂移优化等...
In satisfiability, a propositional formula is used to encode problem specifications in a way that its satisfying interpretations correspond to the solutions of the problem. To find solutions to a problem it is then sufficient to use a satisfiability solver on a correspond- ing formula. Niemela篓,...
The satisfiability problem (Sat) lies at the core of the complexity theory. This is a decision problem: Not the solution itself, but whether or not a solution exists given a specified set of requirements is the central question. Over the... MJH Heule 被引量: 22发表: 2008年 Satometer: ...

Sudoku is a very simple and well-known puzzle that has achieved international popularity in the recent past. This paper addresses the problem of encoding Sudoku puzzles into conjunctive normal form (CNF), and subsequently solving them using polynomial-time propositional satisfiability (SAT) inference ...
Requirements evolution is a research problem that has received little attention hitherto, but deserves much more. For systems to survive in a volatile world, where business needs, government regulations and computing platforms keep changing, software systems must evolve too in order to survive. We di...
In practice one gains even more anonymity than this, because to dispel the disinformation one needs to solve a satisfiability problem, which can be notoriously intractible computationally, although this additional protection may dissipate with time as algorithms improve (e.g. by incorporating ideas ...
is to find afeasible solutioni.e. to assign values to the variables of the model such that every constraint is satisfied. One of the most well-known such problem is theBoolean SATisfiability Problem(boolean SAT). (See WikipediaConstraint satisfaction problemandBoolean satisfiability problementries.)...
