Performance World Changelog
2 August, 2002
New performance tools have been added to analyze non-convex or
discrete models.
29 July, 2002
MINLP type models from the MINLP World have been added to PerformLib.
22 July, 2002
A batch performance processing routine pprocess.gms has been
added, which runs all performance tools automatically.
16 May, 2002:
Added NLP models to the Performance Libraries. The models all come from
the GlobalLib from the Global World. Also renamed PerformanceLib to LINLib
(LP and MIP).
3 April, 2002:
Added new LP Performance Tools. Tools exist for comparing solutions to
best known solution, for comparing solver outcome of two solvers on
a given set of models, comparing resource times of two solvers on a
given set of models, and creating batch files for obtaining performance
measure statistics.
19 March, 2002:
Subdivided plib.zip Performance Library model archive into groups.
Users can download PerformLib either by origin or by model size.
7 February, 2002:
Added best known solution points for most LPs.
31 January, 2002:
Alpha version of Performance Tools published on hidden webpages.
22 January, 2002:
Alpha version of the PERFORMLib published on hidden web pages with 655
models. Library consists of established and new LP and MIP models from
various sources, such as MIPLIB, NEOS, and NETLIB. Includes best known
solution points for selected MIP models.
