Solving huge MIP problem

[Carlos Suazo M.]

Guys,

I am dealing with a very large MIP problem extremely difficult to solve up to MIPGap 1% in a 32 cores machine. You can download the lp file in the following link: http://www.spec.cl/downloads/Tx_INVX_lp.zip

I am wondering if Distributed MIP optimization or any special parameter setting can improve solution time.

Many thanks in advance,

Carlos

Hi Carlos,

Do you have a log file you can post?

Additionally, you might want to take a look at our Automated Parameter Tuning Tool:
https://www.gurobi.com/documentation/6.5/refman/parameter_tuning_tool.html

and the Parameter Guidelines
https://www.gurobi.com/documentation/6.5/refman/parameter_guidelines.html#sec:ParameterGuidelines

Both can help you to find the optimal parameters for your model.

Thanks and best regards,
Sonja Mars
