Solving Restricted Preemptive Scheduling on Parallel Machines with SAT and PMS [PDF]
Journal of Universal Computer Science, 2023 Restricted preemption plays a crucial role in reducing total completion time while controlling preemption overhead. A typical version of restricted preemptive models is k-restricted preemptive scheduling, where preemption is only allowed after a task has

Verifying the DPLL Algorithm in Dafny [PDF]
Electronic Proceedings in Theoretical Computer Science, 2019 Modern high-performance SAT solvers quickly solve large satisfiability instances that occur in practice. If the instance is satisfiable, then the SAT solver can provide a witness which can be checked independently in the form of a satisfying truth ...

An Experimental Survey of Extended Resolution Effects for SAT Solvers on the Pigeonhole Principle
Algorithms, 2022 It has been proven that extended resolution (ER) has more powerful reasoning than general resolution for the pigeonhole principle in Cook’s paper.

Local Consistency and SAT-Solvers [PDF]
Journal of Artificial Intelligence Research, 2010 Local consistency techniques such as k-consistency are a key component of specialised solvers for constraint satisfaction problems. In this paper we show that the power of using k-consistency techniques on a constraint satisfaction problem is precisely captured by using a particular inference rule, which we call negative-hyper-resolution, on the ...

Realization of c-Inference as a SAT Problem
Proceedings of the International Florida Artificial Intelligence Research Society Conference, 2022 Semantically based on Spohn’s ranking functions, c-representations are special ranking models obtained by assigning individual integer impacts to the conditionals in a knowledge base R and by defining the rank of each possible world as the sum of the ...

A Verified Implementation of the DPLL Algorithm in Dafny
Mathematics, 2022 We present a DPLL SAT solver, which we call TrueSAT, developed in the verification-enabled programming language Dafny. We have fully verified the functional correctness of our solver by constructing machine-checked proofs of its soundness, completeness ...

Extending SMTCoq, a Certified Checker for SMT (Extended Abstract) [PDF]
Electronic Proceedings in Theoretical Computer Science, 2016 This extended abstract reports on current progress of SMTCoq, a communication tool between the Coq proof assistant and external SAT and SMT solvers. Based on a checker for generic first-order certificates implemented and proved correct in Coq, SMTCoq ...

A Flexible Proof Format for SAT Solver-Elaborator Communication [PDF]
Logical Methods in Computer Science, 2022 We introduce FRAT, a new proof format for unsatisfiable SAT problems, and its associated toolchain. Compared to DRAT, the FRAT format allows solvers to include more information in proofs to reduce the computational cost of subsequent elaboration to LRAT.

An Effective SAT Solver Utilizing ACO Based on Heterogenous Systems
IEEE Access, 2020 This paper presents new parallel strategies for preprocessing and solving the issue of Boolean Satisfaction (SAT) on Heterogeneous systems of multicore and many-core CPU and Graphics Processing Unit (GPU) using Open Multi-Processor (OpenMP) and NVIDIA ...
