New upper bounds for satis ability in modal K

چکیده
In this paper we present new time and size bounds for satissability in modal K. This is done by means of a simpliied SAT based procedure. Then, as a direct consequence, we provide theoretical support to the claim of superior eeciency for the SAT based decision procedures, with respect to the \classic" tableau based procedures.

Evaluating Optimised Decision Procedures for Propositional Modal K(m) Satis ability
Heavily-optimised decision procedures for propositional modal satisability are now becoming available. Two systems incorporating such procedures for modal K, Dlp and KsatC, are tested on randomly-generated CNF formulae with several sets of parameters, varying the maximum modal depth and ratio of propositional variable to modal subformulae. The results show some easy-hard-easy behaviour, but the...

متن کاملLower bounds for random 3-SAT via di'erential equations
It is widely believed that the probability of satis,ability for random k-SAT formulae exhibits a sharp threshold as a function of their clauses-to-variables ratio. For the most studied case, k = 3, there have been a number of results during the last decade providing upper and lower bounds for the threshold’s potential location. All lower bounds in this vein have been algorithmic, i.e., in each ...
