Version 2.10 has just been released with numerous updates. As before, please let me know if you encounter any problems with the new version so I can correct ASAP!
Changes include:
Updates
- Reorganised OPTI folder structure to reduce the number of folders
- Removed support for LIPSOL and QSOPT (too many LP solvers already)
- Removed supplied demos, replaced with updated examples
- Rebuilt all solvers against MKL v11.1 R3
- Updated IPOPT to v3.11.8
- Updated NLOPT to v2.4.2
- Data fitting weights are now treated as sqrt(weights) internally
New Functionality
- Added RMathLib with a library of statistical functions
- Added ability to calculate fit statistics for NLS/DNLS problems - See NLS Example 7
- Added simple fitting object
optifit - Added automatic plotting of confidence bounds on curve fitting problems - See this NLS Example
- Added C/C++ code generation (including automatic derivatives via CppAD) from SymBuilder models
- SymBuilder now identifies QCQP models
- Added experimental function
optisymfor symbolic derivative generation - Added support for intlinprog (2014a) including opti_ overload
Bug Fixes
- Fixed options bug in opti_nomad with Inf bounds (M. Porcelli)
- Fixed bug in SymBuilder with 0.5 in quadratic programs
- Fixed bug in Cbc incorrectly missing infeasibility in some models
- Fixed bug in derivative checker with Hessian with no NL constraints
