Constructor Details

SeqPrecedeChain

public SeqPrecedeChain(IntVar[] x)

It constructs SeqPrecedeChain.

Parameters:

x - list of arguments x's.

SeqPrecedeChain

public SeqPrecedeChain(List<? extends IntVar> x)

It constructs SeqPrecedeChain.

Parameters:

x - list of arguments x's.

Method Details

getDefaultConsistencyPruningEvent

public int getDefaultConsistencyPruningEvent()

Specified by:

getDefaultConsistencyPruningEvent in class Constraint

consistency

public void consistency(Store store)

Description copied from class: Constraint

It is a (most probably incomplete) consistency function which removes the values from variables domains. Only values which do not have any support in a solution space are removed.

Specified by:

consistency in class Constraint

Parameters:

store - constraint store within which the constraint consistency is being checked.

toString

public String toString()

Description copied from class: Constraint

It produces a string representation of a constraint state.

Overrides:

toString in class Constraint
