ompr.roi 1.0.2.9000
ompr.roi 1.0.2 (2023-09-09)
- Fixes a bug in how the package documentation was specified.
ompr.roi now requires at least R 3.5.0 because ompr requires it.
ompr.roi 1.0.1 (2022-09-05)
ompr.roi does not use a deprecated {Matrix} 1.4-2 function anymore.
ompr.roi 1.0.0 (2022-01-27)
ompr.roi is now licensed MIT.LazyData was removed from the DESCRIPTION file as is produced a
CRAN warning.ROI's status and message information are now part of the returned
solution and can be accessed calling additional_solver_output() on the
returned value.
Breaking changes
- In line with
ROI's way of encoding a general termination status, the
solver_status(result) is now "success" if ROI returned code = 0,
otherwise it is "error".
ompr.roi 0.8.0 (2018-06-11)
Breaking changes
- The package exports column and row duals of LPs. Extracting duals might be solver dependent. Only tested with GLPK. This requires version
0.8 of ompr.
- Minimum supported R version is
3.4.0 since slam also requires >= 3.4
New features
ompr.roi works with other ompr backends as well.ompr.roi always returns a solution, even if the solution status is not optimal. It extracts the ROI solution with force=TRUE.
ompr.roi 0.7.0 (2017-11-18)
Major breaking changes
- The package uses the new sparse matrix interface of
ompr and ROI.
- Minimum supported R version is now
3.3.0
Minor changes
ompr.roi 0.6.1 (2017-10-23)
Bugfix
- Fixed a bug where the
ROI::V_bound object was incorrectly initialised. This causes an error with ROI >= 0.3.0.
ompr.roi 0.6.0 (2017-04-19)
