Hi all,
I'm glad to inform you about new OpenOpt release 0.39 (quarterly since 2007).
OpenOpt is free, even for commercial purposes, cross-platform software for mahematical modeling and (mainstream) optimization. Our website have reached 259 visitors daily, that is same to tomopt.com and ~ 1/3 of gams.com (details).
In the new release:
interalg (medium-scaled solver with specifiable accuracy abs(f-f*) <= fTol): add categorical variables and general logical constraints, many other improvements
Some improvements for automatic differentiation
DerApproximator and some OpenOpt/FuncDesigner functionality now works with PyPy (Python with dinamic compilation, some problems are solved several times faster now)
New solver lsmr for dense/sparse LLSP (linear least squares)
Some bugfixes and some other changes
In our website (http://openopt.org) you could vote for most required OpenOpt Suite development direction(s).
Regards, D.
