Public Member Functions | |
| LinearRelaxSolverMIP (LinearRelax &linrelax_) | |
| void | init () |
| Initializes the model for the core linear relaxation. | |
| void | reset () |
| Resets the solver, so we use only the core linear relaxation. | |
| void | construct (Pointer< MinlpNode > node=NULL) |
| Builds the linear relaxation for a specific node or uses global cuts only. | |
| void | add_cut (const CutPool::CutInfo &cutinfo) |
| Updates the linear relaxation for a specific node. | |
| void | set_objective (Pointer< SepQcFunc > obj) |
| void | update_levelcut (double newlevel) |
| bool | feasible () |
| Checks the linear relaxation only for feasiblity instead of solving it. | |
| int | solve (Pointer< MinlpNode > node=NULL) |
| void | remove_cuts () |
| According to the information, set in the remove-member of the cutinfos, remove cuts. | |
| int | generate_cuts (list< Pointer< SimpleCut > > &cuts) |
Private Member Functions | |
