18 Interface changes

The section shows interface-specific changes to the MOSEK Optimizer API for Java in version 11.0 compared to version 10. See the release notes for general changes and new features of the MOSEK Optimization Suite.

18.1 Important changes compared to version 10

• Parameters. Users who set parameters to tune the performance and numerical properties of the solver (termination criteria, tolerances, solving primal or dual, presolve etc.) are recommended to reevaluate such tuning. It may be that other, or default, parameter settings will be more beneficial in the current version. The hints in Sec. 8 (Debugging Tutorials) may be useful for some cases.

• Renamed getnumanz64 to getnumanz and setdefaults to resetparameters.
