@Deprecated public class LinearConstraint extends Object implements Serializable
Deprecated.
As of 3.1 (to be removed in 4.0).
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.
