Unique solution of Regression

[CatYukino]

Feature Request

Hello. I use SR to fit a dataset, while the result for each running is not the same. For example this is a result of one running:

And this is another:

Here the results are totally different. Is there any settings or hyperparas to make the result unique? :)

If you find a different solution each time (excluding real degeneracies, like how x/2.0 and x*0.5 are identical), then that means you haven’t run the search long enough. Try increasing niterations so it can do a deeper search. Also see https://astroautomata.com/PySR/tuning/ for tips.

If you want identical solution regardless of convergence, you can also use deterministic=True.
