I came across a funny example of problem formation yesterday (cc @Meaningness).
@thilogross, a researcher in Bristol (where I live), showed that Bristol's version of the Königsberg bridge problem (https://en.wikipedia.org/wiki/Seven_Bridges_of_K%C3%B6nigsberg …) *is* soluble, and walked the resulting 33 mile circuit...

The original walk is here: https://www.bristolcivicsociety.org.uk/bristol-bridges-walk/ … (new version at https://reallygross.de/ops/bridgewalk as there are now more bridges!) Now the interesting bit for me is how much of the work was just defining the problem:pic.twitter.com/2ejPqmLgr9

This is great! I’ve actually walked all parts of that, but never considered doing it as a Königsberg circuit

Funny, didn't realise you'd have walked so much of Bristol! I've done a lot of it at some point, but not some of the easternmost bridges or all the ones over the Trym.

Coombe Dingle, Westbury, Blaise Castle area was one of my favorites. Another: Ashton Court out to Dundry. Pub in Dundry is an excellent destination :)

It was closed last time I went, a few years ago now. I hope not for good. The food there was excellent.
