All Implemented Interfaces:

LPConstraintSequence

public class EdgesAsLPConstraintSequence
extends AbstractLPConstraintSequence
implements LPConstraintSequence

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