## 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.

## Member Function Documentation

const char* gubrow_action::name | ( |  | ) | const
| virtual

A name for debug printing.

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

Implements CoinPresolveAction.

|  | const CoinPresolveAction * | next
| ) |  |
| static

void gubrow_action::postsolve | ( | CoinPostsolveMatrix * | prob | ) | const
| virtual

Apply the postsolve transformation for this particular presolve action.

Implements CoinPresolveAction.
