We have just released OpenSolver 2.5 alpha, which has a number of fixes and improvements. It also has some new experimental features.
You now have the ability to select from number of different solvers:
- CBC (included and upgraded to version 2.8.8 in this release)
- Gurobi LP/IP solver (if this is installed on your machine)
- NOMAD non-linear solver (included, supported in 32-bit Office only for now)
- Solvers on the cloud-based NEOS servers – CBC (linear) is supported now, and we hope to offer Couenne and Bonmin (both non-linear) in a future release.
This release also adds reporting of dual variables and sensitivity analysis, and as well as many small bug fixes and feature enhancements. Many thanks to students Matt, Kris, and Jack for their work on these enhancements.
You can download it here. All feedback is welcome, particularly regarding the new experimental features.
Phanks!!!
