Total resistance from unit resistors
This problem is based on, A337517, the most recent OEIS sequence with the keyword "nice".

Oh awesome! Might try my hand. I used some of the code from oeis.org/A048211 which is slightly different. Actually a(5) is the first different number, so I wonder what the unique circuit with 5 resistors that obtains a new value (not obtainable by series and parallel circuits) looks like.

I used slow mathematica code, you have to go to 14 resistors before you can do better than 22/7. I basically just check N cases where N is taken from oeis.org/A000084

Oh, did someone mention Valheim? I can be normal about Valheim. I'm being normal about Valheim right now.

I bring a "I count as 0 views" vibe to the stream that some stream metrics don't appreciate.

Maybe a bit ambitious before bed... Still work to be done to get it in terms of a strict quadratic programming problem (remove the "forall"). But this is what it looks like in terms of a_3, b_3, pretty ugly. On the wiki for quadratic programming, this gives Q and c but not sufficient A or b.
