The complexity of modal satisfiability problems has been investigated since the 1970s, usually proving results on a case-by-case basis. We prove a very general classification for a wide class of relevant logics: Many important subclasses of modal logics can be obtained by restricting the allowed...

The study of random K-SAT problems and of the related solving algorithms is likely to shed light on the origin of the computational complexity and to allow for the development of improved solving algorithms. Both numerical8 and analytical9,10 evidence suggest that a threshold phenomenon takes ...
satisfiability problem A problem used as an example in complexity theory. It can be stated thus: Given a Boolean expression E, decide if there is some assignment to the variables in E such that E is true. ABooleanexpression is composed of Boolean variables, (logical) negation (NOT), (logic...
We also consider the related problem that asks whether we can satisfy {\it all} clauses by flipping the truth values of at most $k$ variables. 展开 关键词: Parameterized complexity Local search Maximum satisfiability DOI: 10.1016/j.disopt.2010.07.003 被引量: 74 ...
