MIPLIB 2010 is a library of mixed integer programming problems which can be obtained
ROI.models.miplib provides utility functions
MIPLIB 2010 and convert it into ROI
optimization problems. Since
MIPLIB 2010 is kind of big only functions
for downloading and accessing the library are provided but not the library itself.
There are two versions of
MIPLIB available at
a smaller version for benchmarking (around 94 MB) and the full version (around 1.3 GB)
which contains all benchmark instances.
Download the benchmark instances.
miplib_download_benchmark(quiet = FALSE)
Download the all instances.
miplib_download_all(quiet = FALSE)
By default the optimization problems are stored in the package folder as
.rds-files and can be accessed via the function
http://miplib.zib.de/ also solutions to the problem instances are
provided which can easily be obtained by executing.
MIPLIB 2010 it can be accessed by the function
miplib() ## or if a non-default folder name was provided at the download step miplib(folder = folder_name)
lists all the names of the (downloaded)
MIPLIB 2010 instances.
miplib(x = "all") ## or if a non-default folder name was provided at the download step miplib(x = "all", folder = folder_name)
gives all the (downloaded)
miplib(x = "metainfo") ## or if a non-default folder name was provided at the download step miplib(x = "metainfo", folder = folder_name)
gives the available meta information.
miplib(x = "rmine6") ## or if a non-default folder name was provided at the download step miplib(x = "rmine6", folder = folder_name)
rmine6 optimization problem as an ROI optimization problem.
ROI_solve( miplib(x = "iis.100.0.cov") )
