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.
