Hello Nigel Unfortunately I could not open the file 'I have a nephew.xps' as XPS interpreters are rare on Gnome/Linux (my only cheap option option is to download and build 'ghostpdl-8.71.tar.bz2'). Could you make this material available as something more universal, perhaps as PDF or PostScript?
Regarding the IAJAAR.H project, I suggest we (and anybody else interested) continue this discussion on the GLPK wikibook page: http://en.wikibooks.org/wiki/GLPK/Sandbox_%28for_content_under_development%29 I marked up some content, but am not sure if this is heading in the right direction. Please note the Wikibooks "discussion" tab. best wishes Robbie > ------------------------------------------------------------ > To: "Robbie Morrison" > Subject: re: [Help-glpk] IAJAAR.H_C-C++.dev.7z > Message-ID: <[email protected]> > From: "Nigel Galloway" <[email protected]> > Date: Fri, 13 Aug 2010 14:18:34 +0100 > ------------------------------------------------------------ > > Thank you for looking at IAJAAR.H.
