Title: Recent Progresses in Local Search for SAT

Speaker: Kaile Su (Peking University)

Venue: Lecture Room (334), 3rd Floor, Building #5, State Key Laboratory of
Computer Science, Institute of Software, Chinese Academy of Sciences

Abstract:

In this talk, I will present some recent progresses in local search for
SAT. In particular, I will introduce the main design and
implementation of a world leading SAT solver CCASat, which is
currently one of the BEST local search solvers for SAT, placed first  in
Random SAT Track (one of three main tracks) in SAT Challenge 2102. A novel
idea in CCASat is the strategy of configuration checking (CC), which is
for the first time proposed for dealing with the cycling problem for MVC
(Minimum Vertices Covering). The idea of CC is indeed leading a paradigm
shift in local search for SAT. It becomes so influential that are used by
near 40% (9 out of 24) solvers in the random SAT category of SAT
Competition 2013, including a gold medal winner and a bronze medal winner.
