Hi Kim,<br><br>I introduced a (serious) bug a few weeks ago by accident - that might explain 0.81.*. <br><br>I fixed it at trunk a few days ago. If you have not updated trunk lately, try that.<br><br>I am at the ICS conference - if I can get wifi in meetings rooms, I'll take a look today.<br>
<br>Thanks,<br>Matt<br><br><br><br><br><div class="gmail_quote">On Sun, Jan 9, 2011 at 5:33 AM, kim <span dir="ltr"><<a href="mailto:kim@hamilton-vejlin.dk">kim@hamilton-vejlin.dk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
For the newer versions of DIP ("0.81.1", "0.81.2" and "trunk") I can no<br>
longer get the examples to work.<br>
<br>
After installation, when I run examples they return simply:<br>
"Alps0240I Processed 0 nodes, has 0 nodes, best relaxed 1e+75, best<br>
feasible 1e+75<br>
<br>
Alps0202I Problem is infeasible. 1 nodes processed, 0 nodes left<br>
Alps0264I No solution found<br>
"<br>
<br>
This is the output from "make test" after installation as well as the<br>
"MILP" and "MILPBlock" examples. I cannot get "GAP" and "MMKP" to<br>
compile at all.<br>
<br>
My install sequence, in case I'm doing something wrong:<br>
1) svn checkout <a href="https://projects.coin-or.org/svn/Dip/releases/0.81.2" target="_blank">https://projects.coin-or.org/svn/Dip/releases/0.81.2</a><br>
Dip-0.81.2<br>
2) cd Dip-0.81.2<br>
3) mkdir build<br>
4) cd build<br>
5) ../configure<br>
6) make<br>
7) make install<br>
8) make test (this is the first time an example unexpectedly returns "no<br>
feasible solution")<br>
9) cd Dip/examples/MILPBlock<br>
10) sh data_extract.sh<br>
11) make<br>
12) ./decomp_milpblock --param milpblock.parm (this too gives a "no<br>
solution" result)<br>
<br>
I have since tried with different instances and with different examples<br>
with the same result.<br>
