<br><font size=1 face="Arial"> </font>
<br><font size=1 face="Arial">Does anyone know how to trace the branch-and-bound
search with Cbc? Actually, I want to know the following information at
each variable branch:</font>
<br><font size=1 face="Arial"> </font>
<br><font size=1 face="Arial">1.</font><font size=1 face="Times New Roman">
</font><font size=1 face="Arial">The solution of the
LP relaxation</font>
<br><font size=1 face="Arial">2.</font><font size=1 face="Times New Roman">
</font><font size=1 face="Arial">The variable is being
branched</font>
<br><font size=1 face="Arial">3.</font><font size=1 face="Times New Roman">
</font><font size=1 face="Arial">The direction of
the branch (left or right?)</font>
<br><font size=1 face="Arial"> </font>
<br><font size=1 face="Arial">Also, what is the default branching heuristic
for Cbc?</font>
<br><font size=1 face="Arial"> </font>
