[Cbc] CbcModel::passInPriorities

[Alexis Guigue]

Dear all,

I have just started working with CBC. As my problem contains some SOS 
constraints of type 1, I got
interested in the example sos.cpp. In this model, what is the advantage 
of identifying these constraints
from the input file and specifically creating CbcObject? Is is to 
improve the branching, i.e.,
by setting higher priority to branching for variables from the SOS 
constraint? It is not very
clear to me what the function ''passInPriorities'' does (see below):

   int * priority = new int[numberSOS];
   // Set SOS priorities high
   CoinFillN(priority,numberSOS,1);
   model.passInPriorities(priority,true);
   delete [] priority;

Thanks in advance

Alexis
