Thank you Dmitrey,
I downloaded the latest tarball (uploaded 08/04/08 00:54:17) and installed it.
Before installing, I erased the older version from the site-packages.
However, the ralg still crashes, at least under windows.
I did not find the bug you mentioned in ralg_oo.py.
Could it be that the bug is caused by my numpy version ?
(on windows I use 1.04 that came with the enthought suite)
Thanks
Eli

Hi Eli,
It seems the bug was due to svn conflict changes
(check your scikits/openopt/solvers/UkrOpt/ralg_oo.py, line 156, svn has
put "<<<<<<< .mine" there).
Try now latest tarball (or use download from subversion, the bug was
absent there)

Examples are absolutely same to nlp1, nlp2, nlp3, nlp_bench_1,
nlp_bench_2 etc.
But the solvers can use only lb<=x<=ub constraints.
