<div class="moz-cite-prefix">Hmm. i am solving the milp problem via
initialSolve() and branchAndBound()....<br>
So i can not use this command...<br>
I mean that i load problem with solver.loadproblem() and then call
initialSolve and branchAndBound.<br>
<br>
By the way, what is the difference between this operation and <br>
CbcModel model(solver1);<br>
model.initialSolve()<br>
model.branchAndBound() ?<br>
<br>
I am asking because if i choose the 2nd method can not solve the
problem after B&B is called...<br>
Thank you!<br>

<br>
I am trying to solve a problem 46614 columns,12540 integers,
42210 rows
<br>
and 125370 nonzero elements.<br>
<br>
After calling initialSolve and 4152 iterations founds
objective close to
<br>
the desirable within seconds.<br>
<br>
After calling branch & bound is trying to find solution ,
and in around
<br>
an hour its simply the program is terminated.<br>
<br>
Do you have any ideas?<br>
