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

A name for debug printing.

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

Implements CoinPresolveAction.
