hi, all<BR>I downloaded 'Ipopt_2005Oct18.tgz' from <A href="http://www.coin-or.org/Tarballs/">http://www.coin-or.org/Tarballs/</A> and after I unzip it, the file contains only one binary file called 'Ipopt_2005Oct18' instead of some proper files. And I also downloaded ipopt-3.0.0.tar.gz there and it works well. I don't know the reason, or is there something wrong with my computer? Or I didn't unzip the tgz file correctly? Thanks for your coming reply!<BR><BR> Regards,<BR> W. Zhang
