Linear-programming Interior Point SOLvers

(Number of access to this page is since 09/05/96)

LIPSOL is a Matlab-based package for solving linear programs by interior-Point methods. For computational efficiency it uses a Fortran package by Esmond Ng and Barry Peyton at ORNL to solve large sparse linear systems. LIPSOL has been tested on the Netlib set of linear programs and has effectively solved all 95 Netlib problems.
