Hi Robbie, My thesis is available online as a pdf at: http://www.collectionscanada.gc.ca/obj/thesescanada/vol2/002/MR60229.PDF Thanks, -Jennie On Mon, Feb 27, 2012 at 5:43 PM, Robbie Morrison <[email protected]> wrote: Hello John and Jennie I think it would be useful to add the code as it stands to the GLPK wikibook (or place it elsewhere and link back) for general reference. I am guessing that Andrew Makhorin may have a view on whether or not to integrate Jennie's code into the mainline. For me, that seems like a reasonable idea. Just wondering if Jennie's thesis is publicly available as a PDF? Perhaps your institution does not place write-ups on the internet or leaves it to the individual student to distribute it the way they wish. The write-up usually is the best source of information about a project, in my experience. Could you check with Jenni perhaps? On behalf of the GLPK community, can I thank Jennie and you for offering to make the code available. best wishes Robbie > -------- Forwarded Message -------- > From: John Chinneck <[email protected]> > To: Noli Sicad <[email protected]> > Cc: Andrew Makhorin <[email protected]>, [email protected] > <[email protected]>, Jennie Pryor <[email protected]> > Subject: Re: Faster Integer-Feasibility in Mixed-Integer Linear Programs > by Branching to Force Change > Date: Sun, 26 Feb 2012 16:54:16 -0500 > > Hi there: > > Jennie Pryor developed the code described in the paper > as part of her master's thesis in Systems and Computer > Engineering at Carleton University.
