<DIV><FONT face=Arial size=2>Dear mailing list,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I just got an error message when I try to solve a
nonconvex MINLP problem using boncouenne from within an AMPL
script.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>There are four files attached to this
message:</FONT></DIV>
<DIV><FONT face=Arial size=2>mymodel.mod is the AMPL model,</FONT></DIV>
<DIV><FONT face=Arial size=2>tmp.dat is the data file,</FONT></DIV>
<DIV><FONT face=Arial size=2>myscript.txt is the AMPL script,</FONT></DIV>
<DIV><FONT face=Arial size=2>log.txt is the captured output of AMPL when it
calls boncouenne .</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The script is called with:</FONT></DIV>
<DIV><FONT face=Arial size=2>ampl myscript.txt</FONT></DIV>
<DIV><FONT face=Arial size=2>,which sets boncouenne as the solver, then the
model and data files are loaded before solving.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm using boncouenne downloaded by SVN from trunk
on 11 august 2008. My OS is Ubuntu Linux Hardy Heron.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Your advice will be appreciated.</FONT></DIV>
