-/*! \relates useless_constraint_action
- \brief Scan constraints looking for useless constraints
-
- A front end to identify useless constraints and hand them to
- useless_constraint_action::presolve() for processing.
-
- In a bit more detail, the routine implements a greedy algorithm that
- identifies a set of necessary constraints. A constraint is necessary if it
- implies a tighter bound on a variable than the original column bound. These
- tighter column bounds are then used to calculate row activity and identify
- constraints that are useless given the presence of the necessary
- constraints.
