Diagnostic Objective Function
Units: | Yes/No |
Default Value: | False (0) |
Validation Rule: | False (0) or True (-1) |
Description: | Write diagnostics for non-zero terms in the objective function. |
Detail: |
Diagnostic Objective Function produces a tab-delimited text diagnostic file that lists all variables that appear in the objective function with a non-zero coefficient and non-zero optimal value along with any objective function constant. It then lists the activity of those variables, such that you can compute term-by-term the elements that make up the complete objective function value.
An example follows:
Step Sample Column Coefficient Value Total
1 1 Constant 1 203092568.3 203092568.3
1 1 GenLoad_MyGen{1} 107.6601211 9 968.9410899
1 1 GenLoad_MyGen{2} 322.9803633 9 2906.8232697000003
1 1 GenLoad_MyGen{3} 538.3006055 9 4844.705449499999
1 1 GenLoad_MyGen{4} 968.9410899 9 8720.4698091
The columns are:
- Step
- The simulation step
- Sample
- The simulation sample (for multi-sample simulations)
- Column
- The name of the column or decision variable in the mathematical programming problem
- Coefficient
- The objective function coefficient of the column/variable
- Value
- The value of the column/variable at the optimal solution (only non-zero values are listed)
- Total
- The production of Coefficient and Value giving the total contribution of that variable to the objective function value
