Yes, the Algorithm changes if you can go back to an earlier partner. You can keep looking further beyond 37% and defer decision making.

I wouldn't recommend dating multiple people at once.

Say your goal is to find your soulmate in next 2 years, let's define n =24 months. Then you keep looking for the next 9 months without committing to any one. Let's say the name of your perfect partner in the first 37% is Max. Then you start looking beyond the first 37%, the first person better than Max is your soulmate. Considering there is chance of refusal or rejection, you can start earlier (follow the above algorithm at 33% )
