Recently it has been shown that many real world problems exhibit numericalal difficulties due to ill-conditioning. This paper describes Lurupa, a software package for computing rigorous bounds for the optimal value of a linear program. The package can handle point and interval problems. Numerical experience with the Netlib lp library is given.en1862-44052006Schloss Dagstuhl Leibniz-Zentrum für Informatiklinear programmingrigorous error boundsnetlibinterval arithmeticInformatikConference Paperhttps://drops.dagstuhl.de/opus/volltexte/2006/445/Other
