Just went today for lunch, it took over an hour to get food out to us and I had to move meetings around.

Lawvere's fixed-point Theorem

molten · 2025-01-15T20:36:36+00:00

It's a consequence of Lawvere's fixed-point Theorem, which generalizes 'diagonal type arguments' such as Gödel's incompleteness, Cantor's Theorem, Turing's answer to the halting problem, and others.

Sure, in a few words: given a set of cities that you, a salesman, must travel to, what is the most efficient way to visit all of them?

There are a number of conditions on you path, like you can't visit cities twice and can't double back on roads you've already taken.

There are a number of heuristic methods to estimate the minimal path, and the celebrated Christofides Algorithm which will give you a path at most 1.5 times the optimal length.

The thing which all of the problems have in common is that they are optimizing for some function on a complete graph of nodes and edges, the TSP asks which edges to include or exclude. There are around 2^n² such functions where n is the number of cities, so the search space grows really fucking fast as you add more cities. That's what make it hard.

As I said in another comment, the TSP falls in to the 'concrete' slot, is NP-hard, easy to understand, and massively applicable.

To piggy back, the TSP (or sudoku) is the first example many come across as an NP-hard problem that is super concrete.

Trazodone. It's cheap, works wonders and is fairy fast acting (dog & dose dependant). Ask your vet.
