Sebastien Poirier commented: Those changes should be driven by benchmarks: it’s not only the order that we can change, but also the weight (time + number of models) given to each grid search: in this case, we should also increase the weight of the DNN grid searches.
Also, still based on benchmarks, let’s see if we can’t change the order/weights for:
Note that the priority order makes sense mainly when the max runtime is small, whereas changing the weight (of grids especially) on top of will have an impact on the proportion of models of each type being trained.

We should consider a re-ordering of the algorithms when there are a high number of classes in the response. For example, perhaps >10 classes, we switch to prioritize GLMs and DNNs over tree-based methods.
