The correct yet disappointing answer is that this isn’t algorithmic. Here are some thoughts though:

  • Prioritize quality friendships, not quality friends
  • Find the right groups. Easier to find likeminded people through a common interest.
  • Be extremely forward. Asymmetric upside on this is insane.
  • Stay in contact

I’m also a noob at making friends though.

Later update: realized this was about finding friends, not making them.
