Reminds me of quantum-bogosort: randomize the list; check if it is sorted. If it is, you're done; otherwise, destroy this universe.

[-] xmunk@sh.itjust.works 96 points 2 weeks ago

Guaranteed to sort the list in nearly instantaneous time and with absolutely no downsides that are capable of objecting.

[-] frezik@midwest.social 48 points 2 weeks ago

You still have to check that it's sorted, which is O(n).

We'll also assume that destroying the universe takes constant time.

[-] BatmanAoD@programming.dev 43 points 2 weeks ago

In the universe where the list is sorted, it doesn't actually matter how long the destruction takes!

[-] groet@feddit.org 13 points 2 weeks ago

It actually takes a few trillion years but its fine because we just stop considering the "failed" universes because they will be gone soon™ anyway.

[-] MBM@lemmings.world 8 points 2 weeks ago

Eh, trillion is a constant

[-] FiskFisk33@startrek.website 8 points 2 weeks ago

amortized O(0)

Well yeah just delete the pointer to it!

[-] PoolloverNathan@programming.dev 2 points 2 weeks ago

universe.take()

[-] vithigar@lemmy.ca 16 points 2 weeks ago

Except you missed a bug in the "check if it's sorted" code and it ends up destroying every universe.

[-] db2@lemmy.world 7 points 2 weeks ago

There's a bug in it now, that's why we're still here.

The creation and destruction of universes is left as an exercise to the reader

[-] BatmanAoD@programming.dev 4 points 2 weeks ago

Creation is easy, assuming the many-worlds interpretation of quantum mechanics!

[-] random72guy@lemmy.world 17 points 2 weeks ago

Instead of destroying the universe, can we destroy prior, failed shuffle/check iterations to retain o(1)? Then we wouldn't have to reload all of creation into RAM.

[-] BatmanAoD@programming.dev 6 points 2 weeks ago

Delete prior iterations of the loop in the same timeline? I'm not sure there's anything in quantum mechanics to permit that...

[-] SubArcticTundra@lemmy.ml 13 points 2 weeks ago

What library are you using for that?

[-] jcg@halubilo.social 29 points 2 weeks ago* (last edited 2 weeks ago)

is-sorted and a handful of about 300 other npm packages. Cloning the repo and installing takes about 16 hours but after that you're pretty much good for the rest of eternity

[-] Swedneck@discuss.tchncs.de 8 points 2 weeks ago

that explains why it took god 7 days to make the universe

[-] onlinepersona@programming.dev 1 points 2 weeks ago* (last edited 2 weeks ago)

We still suffer from the runtime errors that could've been caught at compilation time.

In Python you just use

import destroy_universe
[-] frezik@midwest.social 2 points 2 weeks ago

Since randomizing the list increases entropy, it could theoretically make your cpu cooler just before it destroys the universe.
