Method Detail

setDataStructureFactory

void setDataStructureFactory(D dsf)

Change the internal representation of the constraints. Note that the heuristics must be changed prior to calling that method.

Parameters:

dsf - the internal factory

setLearner

@Deprecated
void setLearner(LearningStrategy<D> learner)

Deprecated. renamed into setLearningStrategy()

Since:

2.2

See Also:

setLearningStrategy(LearningStrategy)

setLearningStrategy

void setLearningStrategy(LearningStrategy<D> strategy)

Allow to change the learning strategy, i.e. to decide which clauses/constraints should be learned by the solver after conflict analysis.

Since:

2.3.3

setSearchParams

void setSearchParams(SearchParams sp)

getSearchParams

SearchParams getSearchParams()

getStats

SolverStats getStats()

setRestartStrategy

void setRestartStrategy(RestartStrategy restarter)

getRestartStrategy

RestartStrategy getRestartStrategy()

setSimplifier

void setSimplifier(SimplificationType simp)

Setup the reason simplification strategy. By default, there is no reason simplification. NOTE THAT REASON SIMPLIFICATION DOES NOT WORK WITH SPECIFIC DATA STRUCTURE FOR HANDLING BOTH BINARY AND TERNARY CLAUSES.

Parameters:

simp - a simplification type.

setSimplifier

void setSimplifier(ISimplifier simp)

Setup the reason simplification strategy. By default, there is no reason simplification. NOTE THAT REASON SIMPLIFICATION IS ONLY ALLOWED FOR WL CLAUSAL data structures. USING REASON SIMPLIFICATION ON CB CLAUSES, CARDINALITY CONSTRAINTS OR PB CONSTRAINTS MIGHT RESULT IN INCORRECT RESULTS.

Parameters:

simp -

getSimplifier

ISimplifier getSimplifier()

setLearnedConstraintsDeletionStrategy

void setLearnedConstraintsDeletionStrategy(LearnedConstraintsDeletionStrategy lcds)

Parameters:

lcds -

Since:

2.1

setLearnedConstraintsDeletionStrategy

void setLearnedConstraintsDeletionStrategy(ConflictTimer timer,
                                         LearnedConstraintsEvaluationType evaluation)

Parameters:

timer - when to apply constraints cleanup.

evaluation - the strategy used to evaluate learned clauses.

Since:

2.3.2

setLearnedConstraintsDeletionStrategy

void setLearnedConstraintsDeletionStrategy(LearnedConstraintsEvaluationType evaluation)

Parameters:

evaluation - the strategy used to evaluate learned clauses.

Since:

2.3.2

getOrder

IOrder getOrder()

setOrder

void setOrder(IOrder h)

setNeedToReduceDB

void setNeedToReduceDB(boolean needToReduceDB)

setLogger

void setLogger(ILogAble out)

getLogger

ILogAble getLogger()

claBumpActivity

void claBumpActivity(Constr confl)

Parameters:

outclause -
