For the parallel execution, each node will get a block of indices beforehand; some may start with large numbers like what you see.

Subject: [CHiPPS] About The Index of AlpsTreeNode when parallel
Dear Professors,
I want to get the index of TreeNode when solving the BIP,
and I have test on a single computer,
the tree node index is form zero to a certain number.
But when I do the same thing on a parallel cluster, I am puzzled.
The index of the first few tree nodes is already so large, such as 1695381798.
I don't know why.
Is this program to be so? If it is this, how do you determine the index?
May You Best Wishes!
