Hey @edfink234,
Only the max size can be specified, as expressions of a particular size need to be iteratively "built up" from smaller expressions.
Cheers,
Miles

Thank you for the reply. Is there a paper or something where it is documented how the expressions are built in PySR? I was looking through the Julia code yesterday and saw a function that seems to generate a random expression that has a parameter for the length of the expression, here. Could this function in principle be used to generate fixed size expressions, or are they not valid (no rules for appending random ops)?
Sorry if the question is unwelcome 😅.
