It has been shown that bounded model checking using a SAT solver can solve many verification problems that would cause BDD based symbolic model checking engines to explode. However, no single algorithmic solution has proven to be totally superior in resolving all types of model checking problems. We present an optimized bounded model checker based on BDDs and describe the advantages and drawbac...

MIMO(Multiple Input Multiple Output) technology was found to exploit the channel richness and spatial diversity, its possible to increase data throughput and reduce the error probability[1]. MIMO channel capacity was derived by Teletar in [2], MIMO find its application in many technology such as HSPA and WLAN. Recent research were devoted to applicability of MIMO to satellite communication and ...

This thesis presents two extensions to the theorem prover Isabelle/HOL, a logical framework based on higher-order logic. The main contribution is a model generator for higher-order logic that proceeds by translating the input formula to propositional logic, so that a standard SAT solver can be employed for the actual model search. The translation is proved correct. The model generator has been ...

The matching design of the source contribute to energy-saving emission reduction vehicles, meet requirements modern society for environmental protection energy-saving. This paper takes pickup truck as research object ratio control strategy self-designed new HMCVT with goal minimizing ...

Modern SAT solvers have experienced a remarkable progress on solving industrial instances. Most of the techniques have been developed after an intensive experimental process. It is believed that these techniques exploit the underlying structure of industrial instances. However, there are few works trying to exactly characterize the main features of this structure. The research community on comp...

We describe a new method for finding finite models of unsorted first-order logic clause sets. The method is a MACE-style method, i.e. it ”flattens” the first-order clauses, and for increasing model sizes, instantiates the resulting clauses into propositional clauses which are consecutively solved by a SAT-solver. We enhance the standard method by using 4 novel techniques: term definitions, whic...
