Ukrainian HI-TECH Initiative


From OpenOpt

Jump to: navigation, search

OpenOpt was created as optimization toolbox for MATLAB/Octave in June 2006.

It had been written by phd student Dmitrey Kroshko, cybernetics institute, NAS Ukraine. Our department has lots of optimization-related code, however, almost all our software is implemented using Fortran or C language, so RAD (rapid application development) is impossible, and OpenOpt was intended to be solution of the problem.

Two first solvers were ralg and ShorEllipsoid, both were implementations of algorithms invented by Naum Z. Shor.

Then, for some reasons, MATLAB/Octave OpenOpt version had been rewritten to Python. Some of the reasons are:

  1. MATLAB is costly, while Python and scipy are 100% free, even w/o copyleft
  2. Object-oriented tools in MATLAB are very badly implemented, at least for now (v. 2007)
  3. Pass-by-copy makes some things very difficult to be implemented.
  4. MATLAB programming constructs are very inconvenient in comparison to Python, for example operator "+=" is absent in MATLAB yet.

As for Octave, according to a message from MATLAB mail list, "all those Octave, SciLab etc are tentative representations of MATLAB, while the latter is tentative representation of anything except matrices". Also, Octave lacks a good IDE, has copyleft restriction (license: GPL, hence it cannot be used by anyone), and depends on Mathworks decisions (to remain MATLAB-compatible), so they can't implement their own features and ideas into language.

OpenOpt was sponsored by GSOC 2007 and 2008.
