WebJun 30, 2015 · Although VSIDS was proposed nearly fifteen years ago, and many other branching heuristics for SAT solving have since been proposed, VSIDS remains one of the most effective branching heuristics. In this paper, we advance our understanding of VSIDS by answering the following key questions. WebC. MapleCOMSPS CHB The difference from COMiniSatPS is that it regularly switches between CHB and VSIDS, in the similar manner as MapleCOMSPS LRB.
