Find a good set of GUROBI parameters to reduce processing time

Currently, the processing time for the optimization with Gurobi is somewhat large for some problems (sometimes > 5 hours), which causes inconvenience for my studies on, for instance, how to define the cost function to achieve the survey progress we desire, where I need to do many simulations changing a sample and cost function for each target, and so on.

The task is to reduce the processing time as much as possible searching for a good set of Gurobi parameters. The test should be done for various problems of not only the galaxy evolution WG but also the GA WG. 

The target processing time is less than 1 hour, which is acceptable for many simulations (just in my feeling).
