Detailed Description

Detect and remove entries whose sum is known.

If we have an equality row where all entries same then For other rows where all entries for that equality row are same then we can delete entries and modify rhs gubrow_action is definitely a work in progress; postsolve is unimplemented.

virtual

Construct a postsolve object and add it to the transformation list.

This is an `add to head' operation. This object will point to the one passed as the parameter. */ CoinPresolveAction(const CoinPresolveAction *next) : next(next) { } modify next (when building rather than passing) inline void setNext(const CoinPresolveAction *nextAction) { next = nextAction; }

/*! A name for debug printing.

It is expected that the name is not stored in the transform itself.

Implements CoinPresolveAction.
