Thanks. Looking for the new location, I find:
http://www.eecs.northwestern.edu/~nocedal/lbfgsb.html
It seems that Prof. Nocedal received permission from the ACM (which
published it and held the copyright) to distribute his code under the
GPL. So, I can now distribute it freely with NLopt, and I will look
into that for a future version. However, because it is GPL, not LGPL,
I would still make it an optional package (configured --with-nocedal
or something like that) as I would rather keep the library at most
under the LGPL. (For one thing, it is of questionable legality to
make a GPL plugin for a non-free program like Matlab.)
However, this is not a high priority right now, as Luksan's
implementation seems to be satisfactory, unless someone can point out
a good reason to prefer Nocedal's code.
