DUALSTRATEGY

Description
This bit-vector control specifies the dual simplex strategy.
Type
Integer
Values
Bit
Meaning
0 
Switch to primal when re-optimization goes dual infeasible and numerically unstable.
1 
When dual intend to switch to primal, stop the solve instead of switching to primal.
2 
Use more aggressive cut-off in MIP search.
3 
Use dual simplex to remove cost perturbations.
4 
Enable more aggressive dual pivoting strategy.
5 
Keep using dual simplex even when it's numerically unstable.
Default value
1
Affects routines
XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
