This change allows to obtain a stable output for the +two tests across different versions of <CODE>glpk</CODE>. +The problem was caused by a change of behavior, first occurring in +<CODE>glpk-4.38</CODE>, in the MPS file parsing routines. +For more details, see the mailing list threads +<A HREF="http://lists.gnu.org/archive/html/bug-glpk/2010-01/msg00005.html">[Bug-glpk] Variables erroneously read as binary?</A> +and +<A HREF="http://www.cs.unipr.it/pipermail/ppl-devel/2011-April/017407.html">[PPL-devel] [Fink-devel] ppl-0.10.2 check thorough test fail</A>. + +The two relevant commits are +<A HREF="http://www.cs.unipr.it/git/gitweb.cgi?p=ppl/ppl.git;a=commit;h=97ce932e012943328164d387cfe9a8d2196ca171">97ce932e012943328164d387cfe9a8d2196ca171</A> +and +<A HREF="http://www.cs.unipr.it/git/gitweb.cgi?p=ppl/ppl.git;a=commit;h=56ee86b9ccf001c8dc2ab1558332e9691b2eff3f">56ee86b9ccf001c8dc2ab1558332e9691b2eff3f</A>. +</DD> + <DT><STRONG>August 15, 2009</STRONG></DT> <DD> Fixed a bug whereby <CODE>maximize</CODE> and <CODE>minimize</CODE>
