Software model synthesis using satisfiability solvers
@article{Heule2012SoftwareMS, title={Software model synthesis using satisfiability solvers}, author={Marijn J. H. Heule and Sicco Verwer}, journal={Empirical Software Engineering}, year={2012}, volume={18}, pages={825-856} }
We introduce a novel approach for synthesis of software models based on identifying deterministic finite state automata. Our approach consists of three important contributions. First, we argue that in order to model software, one should focus mainly on observed executions (positive data), and use the randomly generated failures (negative data) only for testing consistency. We present a new greedy heuristic for this purpose, and show how to integrate it in the state-of-the-art evidence-driven…

It is proved that indeed this algorithm PAC-learns in a stronger sense than the Clark-Thollard algorithm, and is an attempt to keep the rigorous guarantees of the original one but use sample sizes that are not as astronomical as predicted by the theory.

This work shows that BCE is surprisingly effective both in theory and in practice on CNFs resulting from a standard CNF encoding for circuits: without explicit knowledge of the underlying circuit structure, it achieves the same level of simplification as a combination of circuit-level simplifications and previously suggested polarity-based CNF encodings.
