@misselvexu Thanks for your contribution.

I may not have stated it clearly, we just need to delete some of the code and documentation of the optimizer parameters.

The actual memory usage has changed from passing parameters to being calculated by the optimizer itself. This is not deleted immediately for compatibility, but it is no longer effective.

So we need to retain the parameters and calculation logic, and just delete the code associated with parameter parsing.

I'll readjust it，
