Method Detail

propagate

public void propagate()
               throws jopt.csp.variable.PropagationFailureException

Attempts to reduce values in target node domain based on Min / Max values in source node(s)

Specified by:

propagate in interface Arc

Overrides:

propagate in class NodeNumArc

Throws:

jopt.csp.variable.PropagationFailureException - If domain of target node becomes empty
