In talk,I will present some recent progresses and a paradigm shift in local search for SAT.In particular,I will introduce the main design and implementation of a world leading SAT solver CCASat,which 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 in local search for MVC(Minimum Vertices Covering).The idea of CC is 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.
