All Implemented Interfaces:

LPConstraintSequence

public class NodesAsLPConstraintSequence
extends AbstractLPConstraintSequence
implements LPConstraintSequence

An LPConstraintSequence which contains one constraint per node in a graph with numbered nodes. All constraints have the same relation symbol.
