Abstract:
This talk presents our work which for the first time answers the 7th challenge of the 10 challenges of propositional reasoning and search (AAAI 1997, Selman, Kautz, McAllester). Specifically, we propose a hybridizing method for combining systemic search and stochastic search to develop more effective algorithms that outperforms the best previous examples of both approaches. After introducing the CDCL and stochastic local search approaches, I will present the ideas in our hybridizing method, including relaxed CDCL framework, phase resetting, and branching with local search conflict frequency. Our ideas bring significant improvements to state of the art CDCL solvers on standard application benchmarks from the recent 4 SAT competitions as well as an important project.
