XSLP_MIPCUTOFFCOUNT
|
Description
|
Number of SLP iterations to check when considering a node for cutting off
|
|
Type
|
Integer
|
|
Default value
|
5
|
|
Notes
|
If the objective function is worse by a defined amount than the best integer solution obtained so far, then the SLP will be terminated (and the node will be cut off). The node will be cut off at the current SLP iteration if the objective function for the last
XSLP_MIPCUTOFFCOUNT SLP iterations are all worse than the best obtained so far, and the difference is greater than
XSLP_MIPCUTOFF__A and
OBJ * XSLP_MIPCUTOFF__R where
OBJ is the best integer solution obtained so far.
The test is not applied until at least XSLP_MIPCUTOFFLIMIT SLP iterations have been carried out at the current node. |
