New release R20230622
Release with new and improved solver support, and some minor fixes.
Main fixes and additions
- Added support for COPT, thanks to the LEAVES group, RIIS at Shanghai University of Finance and Economics
- Updated support for KNITRO 13.2
- Updated support for XPRESS 9.0
- KKT now supports nonlinearly parameterized models
- Massive performance improvement on large sparse polynomial objectives in nonlinear solvers due to faster gradient computation
- Fixed bug which caused gradient information to be incorrect when EXPCONE models are solved with general nonlinear solvers
- The options bnb.plot and bmibnb.plot now mean the same thing (graphical view of lower/upper bound and stack information)
- Some minor issues which caused issues when upgrading from 2021-verion
