## Detailed Description

We are only going to do this if it does not increase number of elements?.

It could be generalized to more than three but it seems unlikely it would help.

As it is adapted from doubleton icoly is one dropped.

## Member Function Documentation

const char* tripleton_action::name | ( |  | ) | const
| inline virtual

A name for debug printing.

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

Implements CoinPresolveAction.

static const CoinPresolveAction* tripleton_action::presolve | ( | CoinPresolveMatrix * | ,
|  | const CoinPresolveAction * | next
| ) |  |
| static

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

Apply the postsolve transformation for this particular presolve action.

Implements CoinPresolveAction.
