Hello GLPK list
I just applied to Ateji, via their website, for a copy
of their free 'OptimJ' version. They kindly send me
what is probably a Microsoft Windows security key,
judging by the file extension, its binary contents, and
their description, plus instructions for downloading
the main archive.
I think the Ateji team is being a little disingenuous
on this one -- see the forwarded message immediately
below. As far as I can tell, the free 'OptimJ' version
is only free in the sense that no money changes hands
-- it is not free in the Free Software Foundation
sense:
http://en.wikipedia.org/wiki/Free_Software_Definition
I am not suggesting that Ateji is breaking the GNU
GPLv3 through this process -- although I have no
special knowledge in this regard.
But it would help if Atieji could word their
communications with a little more precision -- in
particular, their response to Larry D'Agostino's
inquiry, in my view, could be interpreted as
misleading.
best wishes
Robbie

Coming back to Larry's question below, we have recently
taken the decision to contribute OptimJ to the free
software community. We are now offering a free OptimJ
edition that includes our fully featured Java based
modeling language for optimization along with lp_solve
and GLPK solver links.
More details on www.ateji.com/optimj
Best Regards
The Ateji team

Curious. Why is OptimJ released under a commercial license? It is based
on Java, can be use as an Eclipse plug-in, and uses a number of free
software or open source solvers.
Is Optimj contributing back to the free software community?
I don't mean to call you out on this just wondering why.

Dear all,
It is our pleasure to announce the availability of an OptimJ solver
link for GLPK.
OptimJ is a new Java-based algebraic modeling language with powerful
constructs for data modeling and bulk data processing. Models are
expressed in a high-level mathematical notation and benefit from all
Java libraries and development tools. They can be deployed directly
within any Java-based IT environment.
You'll find more information at http://www.ateji.com/optimj.html,
including whitepapers and code samples. You can also browse the
newsletter archive at http://www.ateji.com/newsletter.html for
specific topics. Questions and comments are welcome in the user forums
at http://forums.ateji.com/.
The software can be downloaded for evaluation at
http://www.ateji.com/downloads.html. Free licences are available for
teachers and students.
Regards,
The Ateji team.
