Changes
- Require
cbcbox>=2.937and expose CBC LP reoptimization method, presolve, and perturbation controls. - Configure primal, dual, barrier, or racing reoptimization independently of the initial LP method. Racing requires at least two threads.
- Apply the selected initial LP method when solving LP relaxations.
- Add regression tests and documentation for repeated LP solves and model changes.
