MIP Strategy Estimate Integer Solution
Type : Selection
Range : The settings listed below
Default : Normal
This option controls the amount of time spent by XA on estimating the value of a would-be integer solution. The rough-estimate method calculates values that are rough estimates, whereas the fast method spends very little time on calculating estimated integer values. These two methods may eliminate nodes that would have led to better integer solutions. Possible values are:
Normal
Rough estimate
Fast
Remark
If you set this option to a non-default value then sometimes the solution time is reduced but XA may not find an optimal integer solution! You should only change the setting of this option if you are interested in obtaining a fast and good integer solution (which may not be optimal).
