mbo_parallel: Parallelization in mlrMBO



In mlrMBO you can parallelize the tuning on two different levels to speed up computation:

Internally the evaluation of the target function is realized with the R package parallelMap. See the mlrMBO tutorial and the Github project pages of parallelMap for instructions on how to set up parallelization. The different levels of parallelization can be specified in parallelStart*. Details for the levels mentioned above are given below:

Details regarding the latter:

single-objective MBO with LCB multi-point

Parallel optimization of LCBs for the lambda-values.

Multi-objective MBO with ParEGO

Parallel optimization of scalarization functions.
