<p>Hi, <br>
</p>
<p>My name is Rita Portugal</p>
<p>I've been working with CBC "inside" C++ language in Visual Studio
framework.</p>
<p>I'm having some strange behavior that I'm hopping you could help
me on understanding it.</p>
<p>I read the input data, create a linear integer model than call
branchAndBound. <br>
</p>
<p>I started by testing a very small example to understand running
time behavior but, while running the same instance and the same
solver configuration several different times (in the same machine)
I'm keep having different time results for getting the same
optimal solution (between 5 minutes to 25).</p>
<p>When reading the user guide I understand that CBC has random
components during is running process that can be desactivate by
the setRandomSeed(7777) comand. But even doing that the behavior
is still the same.</p>
<p>Can you please advise me about any other possible responsable
components for having such a different behavior between runnings?</p>
<p>Thank you in advance<br>
