Solution speed bottleneck

Awaiting user input

I used a new theoretical method to construct a new model. Its solution effect is not bad compared with the old model, but I encountered a bottleneck when I wanted to further optimize its solution speed. Do you have any good suggestions

  Could you elaborate more what exactly you mean by "a bottleneck when I wanted to further optimize its solution speed"?

  One option would be to generate the given model for a small-medium sized data set which can be solved within acceptable time. You could then try to improve Gurobi's performance by tuning its parameters. For that, you can either experiment with the parameters mentioned in Most important parameters or use Gurobi's parameter tuning tool (see Parameter tuning tool and Using the Automatic Parameter Tuning Tool). The reason for using a small-medium sized data set is to not having to wait forever to see whether a parameter has an impact on the solver's performance.
