ompr.roi 1.0.2
- 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
ompr.roi does not use a deprecated {Matrix} 1.4-2
function anymore.
ompr.roi 1.0.0
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
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
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
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
