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

incActivity

public void incActivity(double claInc)

Description copied from interface: Constr

Increase the constraint activity.

Parameters:

claInc -

setActivity

public void setActivity(double claInc)

Description copied from interface: Constr

Set the activity at a specific value

Parameters:

claInc - the new activity
