Objective Function Coefficient Classifier (Signs)
This classifier adds variables \(x_i\) to classes according to the sign of their respective coefficient \(c_i\) in the objective function.
Classification
Dantzig-Wolfe and Benders Decomposition
In both modes, the handling is as follows:
- Three classes are created:
- variables \(x_i\) with \(c_i = 0\)
- variables \(x_i\) with \(c_i > 0\)
- variables \(x_i\) with \(c_i < 0\)
- For each \(x_i\), the respective \(c_i\) is determined and added to the corresponding class (see above).
