idol::Presolvers::StandardScaling Class Reference

#include <idol/mixed-integer/optimizers/presolve/StandardScaling.h>

Description

This class implements standard scaling (a.k.a. equilibration scaling) of the model. For now, it is only performed row-wise since there is no post-processing implemented yet.
