Figure show how frequently the correct structure is at the very top of this list (top-1), within the first five entries (top-5), or within the top-256 entries (the entire GA population). The fraction of times we find the correct structure increases, as expected, if we consider more elements in our ranked list. Interestingly, our system clearly outperforms the current leading approach by around 13 %, providing the correct structure in 76 % of the cases.
