# CROSSOVEROPS

Description | Newton barrier and hybrid gradient: a bit-vector (see Section Bit-vector controls) for adjusting the behavior of the crossover procedure.
Type | Integer
Topic areas | Barrier, Primal Dual Hybrid Gradient, Bit-vector
Values |
Bit | Meaning
0 | Returned solution when the crossover terminates prematurely: 0: Return the last basis from the crossover; 1: Return the barrier solution.
1 | Select the crossover stages to be performed: 0: Perform both crossover stages; 1: Skip second crossover stage.
2 | Set crossover behaviour: 0: Force to perform all pivots; 1: Skip pivots that are numerically less reliable.
3 | Set crossover behaviour: 0: Perform standard crossover; 1: Perform a slower, but numerically more careful crossover.
Default value | 0
Affects routines | XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
