Webb20 okt. 2016 · Now let’s go back to the statement: “The reduced cost of a decision variable (i.e. value 3 for variable x1) is equal to the shadow price of the non-negativity constraint of the variable (i.e. x1 >= 0)”. The shadow price for the constraint x1 >= 0 can be defined as follows: If you increase the right hand side of that constraint (currently ...
