Static Public Member Functions

static const CoinPresolveActionpresolve (CoinPresolveMatrix *prob, const CoinPresolveAction *next, double *rowObjective)

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.
