# Generating only the ranks of elliptic curves that can be found provably correctly

Hello! I am trying to compute the rank for a large number of elliptic curves. I know that this is not always doable in a provably correct manner, so I would like to write up a piece of code that will go through my list of elliptic curves, calculate the rank provably correctly if possible, and skip those elliptic curves for which the rank cannot be computed provably correctly. Is there a simple way to do this? Thanks!
