## Detailed Description

Primal Column Pivot Dantzig Algorithm Class.

This is simplest choice - choose largest infeasibility

## Constructor & Destructor Documentation

AbcPrimalColumnDantzig::AbcPrimalColumnDantzig | ( |  | ) |

Default Constructor.

AbcPrimalColumnDantzig::AbcPrimalColumnDantzig | ( | const AbcPrimalColumnDantzig & |  | ) |

Copy constructor.

virtual AbcPrimalColumnDantzig::~AbcPrimalColumnDantzig | ( |  | ) | `[virtual]`

Destructor.

## Member Function Documentation

virtual int AbcPrimalColumnDantzig::pivotColumn | ( | CoinPartitionedVector * | updates,
|  | CoinPartitionedVector * | spareRow2,
|  | CoinPartitionedVector * | spareColumn1 |
| ) |  |  | `[virtual]`

Returns pivot column, -1 if none.

Lumbers over all columns - slow The Packed CoinIndexedVector updates has cost updates - for normal LP that is just +-weight where a feasibility changed. It also has reduced cost from last iteration in pivot row Can just do full price if you really want to be slow

Implements AbcPrimalColumnPivot.

virtual void AbcPrimalColumnDantzig::saveWeights | ( | AbcSimplex * | model,
|  | int |  |
| ) |  |  | `[inline, virtual]`

Just sets model.

Implements AbcPrimalColumnPivot.

Reimplemented from AbcPrimalColumnPivot.

virtual AbcPrimalColumnPivot* AbcPrimalColumnDantzig::clone | ( | bool | copyData = `true` | ) | const`[virtual]`

Clone.
