The constraint dual value in the current solution (also known as the shadow price).
Given a linear programming problem
and a corresponding dual problem
the Pi
attribute returns .
Of course, not all models fit this canonical form. In general, dual values have the following properties:
- Dual values for
constraints are
.
- Dual values for
constraints are
.
- Dual values for
constraints are unconstrained.
Only available for continuous models.
