By default the first "N" row defined in the ROWS section becomes a
problem's objective; a different objective may be specified in the
OBJNAME section, which contains exactly one data line that names the
objective in field 1. The QSopt parser changes the objective
constraint chosen to be an "N" constraint, if necessary.The
following lines define obj2 to be the objective. Since obj1 is the
first "N" row in the ROWS section QSopt would pick it as objective in
the absence of an explicit choice made in the OBJNAME section.
ROWS
N obj1
N obj2
OBJNAME
obj2
