Are you referring to the one called by the command line ?<br></div></blockquote><div> </div><div>I'm specifically talking about the branchAndBound member functions on the solvers/solver interfaces, called for instance as:<br>

Cbc has strong branching, cuts and heuristics, it is not a "pure"
B&B - it should be smarter than CLP in most cases.<br></div></blockquote><div>Ok, great, thanks for the tip!</div><div><br></div><div>As a side note, the served doxygen documentation is behind some sort of password wall, e.g.: <a href="http://www.coin-or.org/Doxygen/Clp/hierarchy.html">http://www.coin-or.org/Doxygen/Clp/hierarchy.html</a>.</div>

Clp has a pure branch and bound.<br>

<div>I was curious if there are any publications or additional
documentation on the branch and bound methods implemented in
the Cbc and Clp models (assuming there is a difference)?<br clear="all">
