Abnormal termination of Optimisation

Hello,

 

We have been running a quit heavy optimisation with hyperstudy using the GRSM algorithm.

After about 37 runs, the computer stopped or we had a power cut or something, so we had an abnormal termination of the optimisation.

 

Is there a way to restart the optimisation from where it stopped instead of running the whole thing again? It is a very heavy opt, so it took us a day and a half to run up to iteration 37, and it would be very important for us to just restart from where left.

 

Many thanks in advance.

    Please take look in to online help document for termination of GRSM based optimization. Meanwhile I will check for some best practices GRSM based optimization and alternate solution your query.

    Please find below comment from my colleague to retrieve old run

     

    For the abnormal termination, you need to do the following:

    • Right click on the previously aborted optimization, select Copy (it will create a new optimization approach, a copy of the previous one)
    • Then in Specifications, click on More... and enable Use Inclusion Matrix Without initial
    • Once Inclusion matrix option is enabled click on Edit Matrix at the top right corner
    • Click on Inclusion Matrix -> Import values-> select Approach evaluation data -> select Optimization 1 (the stopped one) and import the runs already done

    After this, the runs that have already solved will be included in the new optimization approach will not be lost.
