MIPABSCUTOFF


Description
Branch and Bound: If the user knows that they are interested only in values of the objective function which are better than some value, this can be assigned to MIPABSCUTOFF. This allows the Optimizer to ignore solving any nodes which may yield worse objective values, saving solution time. It is set automatically after an LP Optimizer command, unless it was previously set by the user. The cutoff may be updated automatically whenever a MIP solution is found using the MIPRELCUTOFF and MIPADDCUTOFF controls.
Type
Double
Default value
1.0E+40 (for minimization problems); -1.0E+40 (for maximization problems).
Notes
MIPABSCUTOFF can also be used to stop the dual algorithm.
