OriginalHTClause

public OriginalHTClause(IVecInt ps,
                        ILits voc)
Method Detail

register

public void register()
Description copied from interface: Constr
Register the constraint to the solver.


learnt

public boolean learnt()
Returns:
true iff the clause was learnt during the search

setLearnt

public void setLearnt()
Description copied from interface: Constr
Mark a constraint as learnt.


brandNewClause

public static OriginalHTClause brandNewClause(UnitPropagationListener s,
                                              ILits voc,
                                              IVecInt literals)
Creates a brand new clause, presumably from external data.

Parameters:
s - the object responsible for unit propagation
voc - the vocabulary
literals - the literals to store in the clause
Returns:
the created clause or null if the clause should be ignored (tautology for example)

forwardActivity

public void forwardActivity(double claInc)

incActivity

public void incActivity(double claInc)
Description copied from interface: Constr
Increase the constraint activity.

Parameters:
claInc -
