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.
