We are pleased to announce the release of GenOpt 2.1.0.

GenOpt is a freely available open-source optimization program for the
minimization of a cost function (such as annual energy use, peak
electrical demand, utility cost, etc.) that is evaluated by an external
simulation program.

For example, you can compute a building's annual energy cost in
EnergyPlus, TRNSYS, IDA, DOE-2, or any simulation program with
text-based input and output, and let GenOpt automatically find the
values of selected parameters that yield lowest cost.

GenOpt has a library with local and global multi-dimensional and
one-dimensional optimization algorithms, as well as algorithms for doing
parametric studies.
