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 > ------------------------------------------------------------ > To: [email protected] > Subject: [Fwd: RE: [Help-glpk] ANNOUNCEMENT: OptimJ solver link for > Message-ID: <1295349022.3392.0.camel@none> > From: Andrew Makhorin <[email protected]> > Date: Tue, 18 Jan 2011 14:10:22 +0300 > ------------------------------------------------------------ > > -------- Forwarded Message -------- > From: chtimax <[email protected]> > To: [email protected] > Subject: RE: [Help-glpk] ANNOUNCEMENT: OptimJ solver link for GLPK/Java > Date: Tue, 18 Jan 2011 01:30:21 -0800 (PST) > > Coming back to Larry's question below, we have recently > taken the decision to contribute OptimJ to the free > software community.
