## Detailed Description

For variables with one entry.

If we have a variable with one entry and no cost then we can transform the row from E to G etc. If there is a row objective region then we may be able to do this even with a cost.

## Member Function Documentation

const char* slack_singleton_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]`

void slack_singleton_action::postsolve | ( | CoinPostsolveMatrix * | prob | ) | const`[virtual]`

Apply the postsolve transformation for this particular presolve action.

Implements CoinPresolveAction.
