Optimization speed is unexpected slow #4
Description
Heyy Simone,
Thanks very much for your repo, I like it a lot!
However, when I run Solomon instance C101 with 20 customers on your repo, the solution time would be around 40 minutes, which is a bit too slow, no?
When I ran the same instance with the default Gurobi solver (I am not sure which method it is used, maybe cut-pricing?), it would only take around 1.2 seconds...
Do you have any idea about the reasons for the slow solution time?
BTW My hardware is AMD EPYC 7313P
BW,
