Custom Generation Strategy

What are Custom Generation Strategies?

The default generation strategy is generate n points randomly, then, m points with a systematic model .
But under certain circumstances, you may need a more complex strategy, for example, first generating 10 pseudorandom points, then searching them with BOTORCH_MODULAR, then searching 20 pseudorandom again, and then 10 SAASBO. This is possible with OmniOpt2, and the way to do it is to use a custom generation strategy .

How to enter them in the GUI

Click the Show additional parameters button, then scroll down to Generation Strategy . Enter the list of models with an equal-sign and the number of jobs that should be executed with them, like given in the example.

How to add it manually to an OmniOpt2-job

It's simple: just add this command line argument to your OmniOpt2-call:

--generation_strategy SOBOL=10,BOTORCH_MODULAR=20,SOBOL=10

Of cource, change it according to your needs.

Caveats

• Currently, the custom Generation Strategy does not work with PSEUDORANDOM , RANDOMFOREST and EXTERNAL_GENERATOR
• Jobs with custom generation strategies cannot be continued
