The Libopt environment is both a methodology and a set of tools that can be used for testing, comparing, and profiling solvers on problems belonging to various collections. These collections can be heterogeneous  in the sense that their problems can have common features that differ from one collection to the other. Libopt brings a unified view on this composite world by offering, for example, the possibility to run any solver on any problem compatible with it, using the same Unix/Linux command. The environment also provides tools for comparing the results obtained by solvers on a specified set of problems. Most of the scripts going with the Libopt environment have been written in Perl.

A detailed description of the Libopt environment can be found in the documentation.

The current standard distribution of Libopt provides an interface for the cells that are colored in the following {solvers} x {collections} Cartesian product:

Cr Cst MM Mo Mo.T Mo.M
fmincon
lbfgs
lbfgsb (2.1)
m1qn3 (3.3)
n1cv2
n2qn1 (2.1)
qpalm (1.0)
quadprog
sqplab (0.4.4)
sqppro (0.5)

where we have abbreviated the collection names as follows: We plan to enrich the environment in the future versions.
