In Branch and Bound the dual simplex algorithm is normally used
and some network "tricks" only work with primal. Clp (and so Cbc)
can be faster it told that it has a network.<br>
<br>
BUT the minute you add cuts, it is no longer a network and in 99%
of cases Branch and Bound is much faster with cuts.<br>

<div>Hi All,<br>
</div>
I was wondering if it's possible to configure CBC (an
argument?) in order to use a "network" solver (which, for
network structured matrices should be much faster than
normal simplex), but I couldn't find any information about
this... is it available ?<br>
<br>
</div>
Thanks in advance,<br>
