what's curious? so it was said a couple of months ago in this thread in dialogues with my participation)) here many argued that max/min ff should not be in any way))))
as you set the ff so the ship will sail....
You still don't understand: it's not about optimisation at all - it's a tool to create a teacher for learning.
There are only a few problems in MOE and the first one is a good teacher.
And the quality of the teacher is NOT determined by the quality of the FF and is not determined by the quality of the optimisation - earlier we were talking about local/global optimum. In the example we didn't bother and took the first algorithm and used it head-on, which is absolutely right.
The quality of the teacher is determined by the ability to select predictors that will not lose their predictive power in the future. But when determining this property of the teacher, FF is not used at all.

No. You still don't get it. Without optimisation there can be no MoE in principle. without optimisation nothing can exist at all. nothing at all.
What is a "clever teacher"? Where are the criteria of conformity to this clever teacher? You are going to evaluate the conformity of the model to the teacher. The evaluation of conformity is the FF, how can you not understand elementary things.
The FF is the evaluation criteria. Optimisation means maximising the evaluation criteria.No. You don't understand, you don't understand. Without optimisation, there can be no MO without optimisation. without optimisation, nothing can exist at all. nothing at all.

I'll add.
Using optimisation when creating a teacher is one thing, is external to the model.
Using optimisation when searching for model parameters is another, it is built into the model itself, there are models where you can choose the optimisation option.
Evaluating the use of the classification model is the third and there is no smell of optimisation here. There is its own system of classification error estimation.
For example, the error matrix

It's kind of a fork in the road here. The topic under discussion has turned to reinforcement learning, and maybe it makes sense to use all approaches from there. In trading, it has proved itself to be about nothing so far. Either it is training with a teacher using ready-made examples. Or unknown crossed rhinos of this and that, but there is not even any theoretical apparatus for it :)
Here is https://www.mql5.com/ru/code/903 also 11 years ago. And the chart is prettier than mytarmailS in his example.
But I don't think it's yours. Where is yours?

Here before the training, and he has it after. So he doesn't just mark it up nicely
