<div dir="ltr"><div><div>Hi Haroldo,<br><br></div>It's been a while since we worked with the applications. We have recently been focused on using Dip as a generic decomposition-based MILP solver and on its use through Dippy. It seems we have mucked up a few things with the C++ application development. I am sorting it out now and will get back to you soon.<br><br></div>Cheers,<br><br>Ted<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Dec 7, 2014 at 8:53 PM, Haroldo Gambini Santos <span dir="ltr"><<a href="mailto:haroldo.santos@gmail.com" target="_blank">haroldo.santos@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I've run before the two scripts <br>

So I think that the instances were downloaded.<div><div class="h5"><br>

Hi Ted,<br>
<br>
I'm running using trunk revision 1174.<br>
<br>
I'll try the stable release. I would prefer DIP (over DipPy)
because I'm not a python programmer...<br>
<br>
Cheers<br>

What version are you using? There are some bugs I need to
clean up (and it's on my short-term TODO list), but the
releases should all work properly I think. I'll try to
replicate your issue once I have the version. By the way, if
you know Python. DipPy is a bit more convenient to work with
and gives you most of the same power as the C++ interface
with perhaps a little loss in efficiency, depending on what
you're doing.<br>
<br>
Cheers,<br>

<br>
I'm trying to start using DIP for some of my
applications.<br>
<br>
Initially I'm trying to run the examples to better
understand the framework.<br>
<br>
I've succeeded in running the MCF example, but when I
try to run the GAP example I got the following error:<br>

Could someone give me some help ?<br>
