XSLP_BARSTARTOPS

Description
Controls behaviour when the barrier is used to solve the linearizations
Type
Integer
Values
Bit
Meaning
0 
Check objective progress when no crossover is applied.
1 
Fall back to dual simplex if too many numerical problems are reported by the barrier.
2 
If a non-vertex converged solution found by barrier without crossover can be returned as a final solution.
Default value
-1
Note

The following constants are provided for setting these bits:
