ompr.roi 1.0.2
- Fixes a bug in how the package documentation was specified.
- ompr.roinow requires at least R 3.5.0 because- omprrequires it.
ompr.roi 1.0.1
- ompr.roidoes not use a deprecated {Matrix} 1.4-2
function anymore.
ompr.roi 1.0.0
- ompr.roiis now licensed MIT.
- LazyDatawas removed from the- DESCRIPTIONfile as is produced a CRAN warning.
- ROI’s- statusand- messageinformation 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, thesolver_status(result)is now"success"ifROIreturnedcode = 0, otherwise it is"error".
ompr.roi 0.8.0
Breaking changes
- The package exports column and row duals of LPs. Extracting duals
might be solver dependent. Only tested with GLPK. This requires version
0.8of ompr.
- Minimum supported R version is 3.4.0sinceslamalso requires>= 3.4
New features
- ompr.roiworks with other- omprbackends as
well.
- ompr.roialways returns a solution, even if the
solution status is not optimal. It extracts the- ROIsolution with- force=TRUE.
ompr.roi 0.7.0
Major breaking changes
- The package uses the new sparse matrix interface of
omprandROI.
- Minimum supported R version is now 3.3.0
Minor changes
ompr.roi 0.6.1
Bugfix
- Fixed a bug where the ROI::V_boundobject was
incorrectly initialised. This causes an error withROI>= 0.3.0.
