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 MIP cutoff tests are only applied after
XSLP_MIPCUTOFF_LIMIT SLP
iterations at the current node.
