## Detailed Description

Primal Column Pivot Dantzig Algorithm Class.

This is simplest choice - choose largest infeasibility

## Constructor & Destructor Documentation

ClpPrimalQuadraticDantzig::ClpPrimalQuadraticDantzig | ( |  | ) |

Default Constructor.

ClpPrimalQuadraticDantzig::ClpPrimalQuadraticDantzig | ( | const ClpPrimalQuadraticDantzig & |  | ) |

Copy constructor.

ClpPrimalQuadraticDantzig::ClpPrimalQuadraticDantzig | ( | ClpSimplexPrimalQuadratic * | model,
|  | ClpQuadraticInfo * | info |
| ) |  |  |

Constructor from model.

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

Destructor.

## Member Function Documentation

virtual int ClpPrimalQuadraticDantzig::pivotColumn | ( | CoinIndexedVector * | updates,
|  | CoinIndexedVector * | spareRow1,
|  | CoinIndexedVector * | spareRow2,
|  | CoinIndexedVector * | spareColumn1,
|  | CoinIndexedVector * | spareColumn2 |
| ) |  |  | `[virtual]`

Returns pivot column, -1 if none.

Lumbers over all columns - slow updateArray has cost updates (also use pivotRow_ from last iteration) Can just do full price if you really want to be slow

Implements ClpPrimalColumnPivot.

virtual void ClpPrimalQuadraticDantzig::saveWeights | ( | ClpSimplex * | model,
|  | int | mode |
| ) |  |  | `[inline, virtual]`

Just sets model.

Implements ClpPrimalColumnPivot.

ClpPrimalQuadraticDantzig& ClpPrimalQuadraticDantzig::operator= | ( | const ClpPrimalQuadraticDantzig & | rhs | ) |

Assignment operator.

virtual ClpPrimalColumnPivot* ClpPrimalQuadraticDantzig::clone | ( | bool | copyData = `true` | ) | const`[virtual]`

Clone.

Implements ClpPrimalColumnPivot.
