Class NoLearningNoHeuristics<D extends DataStructureFactory>

java.lang.Object

org.sat4j.minisat.learning.NoLearningNoHeuristics<D>

All Implemented Interfaces:

Serializable, LearningStrategy<D>

public final class NoLearningNoHeuristics<D extends DataStructureFactory>
extends Object

Allows MiniSAT to do backjumping without learning. The literals appearing in the reason do not see their activity increased. That solution looks the best for VLIW-SAT-1.0 benchmarks (1346s vs 1785s).
