Method Detail

assertConstraint

public void assertConstraint(UnitPropagationListener s)

Description copied from interface: Constr

Method called when the constraint is to be asserted. It means that the constraint was learnt during the search and it should now propagate some truth values. In the clausal case, only one literal should be propagated. In other cases, it might be different.

Specified by:

assertConstraint in interface Constr

Overrides:

assertConstraint in class HTClause

Parameters:

s - a UnitPropagationListener to use for unit propagation.

computeAnImpliedClause

getDegree

public BigInteger getDegree()

Specified by:
