Thank you for your comments.
BTW, do you have an
optional specification file algencan.dat
that you can send me ?
I just noticed the message
The optional specification file algencan.dat was not
found in the current
directory (this is not a problem nor an error). The
default values for the
ALGENCAN parameters will be used.

ALGENCAN has finished solving the problem unnamed
