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
