Detailed Description
Constructor & Destructor Documentation
Member Function Documentation
|
virtual |
Pack the initial information (info that the user wants to send over) for the process specified by the last argument.
The information packed here will be unpacked in the unpack_module_data() method of the user defined class in the appropriate process.
Default: empty method.
Reimplemented from BCP_tm_user.
Definition at line 16 of file BM_pack.cpp.
|
virtual |
Pass the core constraints and core variables to bcp.
Reimplemented from BCP_tm_user.
|
virtual |
Create the set of extra variables and cuts that should be added to the formulation in the root node.
Also decide how variable pricing shuld be done, that is, if column generation is requested in the init_new_phase() method of this class then column generation should be performed according to pricing_status.
Reimplemented from BCP_tm_user.
|
virtual |
Print a feasible solution.
Reimplemented from BCP_tm_user.
|
virtual |
Process a message that has been sent by another process' user part to this process' user part.
Reimplemented from BCP_tm_user.
| void BM_tm::receive_pseudo_cost_update | ( | BCP_buffer & | buf | ) |
| void BM_tm::pack_pseudo_costs | ( | BCP_buffer & | buf | ) |
|
virtual |
Output the final solution.
Reimplemented from BCP_tm_user.
|
virtual |
Do whatever initialization is necessary before the phase-th phase.
(E.g., setting the pricing strategy.)
Reimplemented from BCP_tm_user.
