Branch-and-price solver for the Feeder Network Design Problem
License: GNU General Public License v3.0
Hello,
The paper says the best-first strategy is applied, with which the node whose parent has the highest lower bound (father_lb
) will be explored first. However, the priority_queue in the code is a min-heap in which the node with smaller father_lb
has higher priority. So it seems they are inconsistent? Did I miss something?
This is also verified by BBTree::update_lb()
in which the top element in priority_queue is used to update the global lower bound. This is valid in the min-heap case.
Thanks you!
I have a maritime routing problem where each port produces a constant rate of goods every time period and consumes a constant rate of some other good. Does this algorithm allow fidnign solutions that prevent the cache at each port either emptying or filling completly?
Hi,
I tried to compile your code. It gives me this error:
