Made me laugh while drinking; messy, but worth it for the smiles I'll have every time I remember it! Outstanding job, internet stranger.
Makes me wonder how many times my parents wondered whether we were going to make it/had to pretend everything was going to be okay.
The 'Wilderness Girls' scene in Loaded Weapon 1 will forever be in my heart and laughter; https://www.youtube.com/watch?v=kRN2spEualo
It tears me up inside to think that we might not even have food and water by the time they get there, let alone the level of pretend we have to maintain so that their childhood is preserved now.
The second you wield a language which has constructs like Haskell, where in theory you can iterate over an infinite list of items (thinking about it even any language where for i in input_var is possible); the halting problem hits you in the face like a brick.
Its almost a chicken and the egg problem, where you can't know how long it will run for/whether it will halt without already knowing the answer, but if you knew the answer, you wouldn't need the program to find it.
My head is spinning.
Regarding the downcast/upcast; I think it _can_ be possible to do this successfully;
> I have a glass, I throw it at a hard surface. What will happen? Well (duh) the glass will (most likely) break.
This hypothesis completely ignores nearly 100% of all relevant physics and the laws surrounding the problem; the arrangement of air molecules, the arrangement of the molecules in the glass, the physical forces governing me, it reduces the entire equation down to some really basic napkin physics.
But; does the outcome work? Has my interpretation of the universe and its physics actually predicted what will happen?
Probably a stupid example, but I think that a lossy picture of the universe can still yield a correct answer.
I can't physically run a simulation of the entire universe in my brain, as my brain is part of that same universe. Lossy representations/models are a necessity in the thinking-ham bound world in which we exist.
The approach you describe though is brute force. I don't think (if there even is an answer to this problem) that it can be brute forced; that's where you run into the limits of hardware/computation/energy and start talking about timeframes which exceed the life of the universe.
I think brute force might be a useful tool in places to validate results, but if there _is_ an answer to this problem it's purely mathematical.
Apologies for sounding both excited and naive; these sorts of challenges make me happy in strange ways that no other thing does!
- How long does it take to get from A to B? => Easy if you know where A and B are, and what mode of transport you're taking to get there.
- How long does it take to get from A to _somewhere_ => As long as it takes!!
