Hi. I tried using the dimacs-solver on <a href="http://big1.net">big1.net</a> from:<br> <a href="http://ftp.zib.de/pub/mp-testdata/mincost/netg/index.html">http://ftp.zib.de/pub/mp-testdata/mincost/netg/index.html</a><br>
<br>The LEMON solution states MinFlowCost: 506,515,059.<br><br>However, when I formulate this as a linear program and solve with an LP solver, I get: 3.48662534E+10.<br><br>I also checked with Cplex (which has a Dimacs parser) and it also got 3.48662534E+10 as the optimal flow.<br>
<br>Is this a bug?<br><br>Thanks,<br>Matt<br><br><br>
