| Title: | 'ROI' Optimization Problems Based on 'NETLIB-LP' |
|---|---|
| Description: | A collection of 'ROI' optimization problems based on the 'NETLIB-LP' collection. 'Netlib' is a software repository, which amongst many other software for scientific computing contains a collection of linear programming problems. The purpose of this package is to make this problems easily accessible from 'R' as 'ROI' optimization problems. |

If x is missing a character vector giving the names of all available problems is
returned. If x is "all" a list containing all the optimization problems
is returned. If x is the name of an optimization problem, the given optimization
problem is returned. If x is "metainfo" a data.frame containing all the
meta info is returned.

Netlib is a software repository, which amongst many other software for
scientific computing contains a collection of linear programming
problems. The column optimal\_value contains the
results published in Koch (2004).
