Hi,

I obtain dual values for a resource constraint in my LP using the main() script. I notice that the bounds for this resource do not change. When I add a unit to this resource and resolve, my objective does go up but not by the amount i received as dual in the first solve. Can anyone help me understand what this means?

Thanks,

Hi,

the dual value is the infinitesimal change in the objective function arising from an infinitesimal change in the constraint.

Can you try with less than a unit ?
