## Constructor & Destructor Documentation

CglFakeClique::CglFakeClique | ( | const CglFakeClique & | rhs | ) |

Copy constructor.

CglFakeClique::CglFakeClique | ( | OsiSolverInterface * | solver = `NULL`,
|  | bool | setPacking = `false` |
| ) |  |  |

Default constructor.

If the setPacking argument is set to true then CglFakeClique will assume that the problem in the solverinterface passed to the generateCuts() method describes a set packing problem, i.e.,

- all variables are binary
- the matrix is a 0-1 matrix
- all constraints are '= 1' or '<= 1'

Otherwise the user can use the considerRows() method to set the list of clique rows, that is,

- all coeffs corresponding to binary variables at fractional level is 1
- all other coeffs are non-negative
- the constraint is '= 1' or '<= 1'.

If the user does not set the list of clique rows then CglFakeClique will start the generateCuts() methods by scanning the matrix for them.

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

Destructor.

## Member Function Documentation

virtual CglCutGenerator* CglFakeClique::clone | ( |  | ) | const`[virtual]`

Clone.

Reimplemented from CglClique.

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

Assignment operator.

virtual void CglFakeClique::generateCuts | ( | const OsiSolverInterface & | si,
|  | OsiCuts & | cs,
|  | const CglTreeInfo | info = `CglTreeInfo()` |
| ) |  |  | const`[virtual]`

Generate cuts for the model data contained in si.

The generated cuts are inserted into and returned in the collection of cuts cs.

Reimplemented from CglClique.

void CglFakeClique::assignSolver | ( | OsiSolverInterface * | fakeSolver | ) |

Assign solver (generator takes over ownership).
