Hi,

I am currently using version 9.1.2 of Gurubipy. Using Jupyter notebook to run the code . For a VRP optimization problem, my kernel is always getting killed.

An instance :

  Given the extremely large number of open nodes. I am pretty sure that you run into an out-of-memory condition. The article How do I avoid an out-of-memory condition? should be helpful.
