public class LinearConstraint
extends Object
implements Serializable
A linear constraint for a linear optimization problem.

A linear constraint has one of the forms:

• c1x1 + ... cnxn = v
• c1x1 + ... cnxn <= v
• c1x1 + ... cnxn >= v
• l1x1 + ... lnxn + lcst = r1x1 + ... rnxn + rcst
• l1x1 + ... lnxn + lcst <= r1x1 + ... rnxn + rcst
• l1x1 + ... lnxn + lcst >= r1x1 + ... rnxn + rcst
The ci, li or ri are the coefficients of the constraints, the xi are the coordinates of the current point and v is the value of the constraint.
