[CHiPPS] Reduce the Memory Size of one Tree Node

[化高峰]

Dear Professors,I am trying to use BLIS to solve a 0,1 problem.
Depth-first can do the job, and find just two Feasible solution.
Best-first can not solve the problem. Maybe there are two many candidates or Treeodes, so the memory of the machine is exhausted, and Blis will quit with one of the task killed(MPI).
I am wondering if the size of one Treenode could be reduced. Just store some useful data.
Up to now, I just need the index, parent index, children index, depth and status of one node. Could I just use these variable and comment out other variable?
Or is there any way to reduce the size of one TreeNode?


Wish you all the best!
