    I am using CPLEX Python API to optimize a MIP problem but the best bound is moving very slowly (maybe even 0.01 improvement in one hour). I am new to this interface so could you please tell me which parameter can I use to speed up this process?

    You may want to take a look at Troubleshooting MIP performance issues in the user manual. If you cannot find anything there then you should at least post a log file here or maybe even share your model (exported via Cplex.write('model.sav.gz')) either here or with daniel(dot)junglas(at)de(dot)ibm(dot)com. Without more information it is hard to tell where time is burnt for your model.
