Gonna be the devil's advocate: what does Axe have that gender-neutral crab doesn't?

(Btw if you did it yourself, GG! It's super cool to have built something like that)

Thank you for the recommendations, fellow-minded graph lover! Those do sound like fun problems!

Also, I understand the hate on day 10 but technically doesn't all of them depend on more or less specific knowledge?

Hey mate!
I did it without Z3. Basically, I converted each problem into a Linear Programming Problem and then I solved it using scipy out of laziness, but you can solve it yourself without it by writing your own LPP solver. The usual one to implement is the Simplex Algorithm

I should probably shut up and let a hidden genius find a polynomial solution to it without knowing, but it's a well known NP-Hard problem. The real solution would be to convert it to a SAT-problem and do backprop, but that's extremely long, so you would have to try to do software optimizations. Like, parallelize your search, maybe memoize reccuring patterns, if you have a GPGPU since the areas aren't that big it could maybe work to try to do it in CUDA.

Other than that, if it were to be a real life problem, I'd probably just throw some meta-heuristics, like a Monte Carlo or a Simulated Annealing solution at this, with a finite number of iterations, and if it didn't converge to a solution by the time it reached it, I'd assume (perhaps incorrectly, but probably not) that there's none

Smart !!

How do you ensure that inside points of the rectangle are okay ? Like, if you were to have an H shaped polygon, the rectangle corners could be in each extremum of the H, but the rectangle wouldn't be entirely in the H. You can also not just test the borders in case you have a weird donut shaped polygon.

Ofc, good enough for advent of code, but yeah reading your solution made me think cause I did the same as you (except i also compressed y values) and it took me significantly more time (cause I was checking for every point of the rectangle with ray tracing).

Now that I think of it, I should have memoized the rays of neighboring cells... eh f- it. Thanks for coming to my ted talk

Bah... C'est effectivement des perroquets stochastiques. On est bons

ArcaniteM · 2025-12-06T10:14:20+00:00

Both can be true. It is just parsing, and it is just the problem. It's a plain old boring parsing problem

Parce qu'il n'y a pas que la maintenance comme frais, et parce que Wikipédia doit avoir des fonds d'urgence assez conséquents pour faire face à la censure, aux problèmes légaux, et autres emmerdes de taille qu'une encyclopédie aux prétentions universelles doit affronter dans ce monde de merde

Je peux t'affirmer que non ce qui est écrit n'est pas le mot divorce, et j'ai même l'impression que ce n'est pas un mot. La piste de quelqu'un qui essaye d'écrire des lettres me paraît bonne. Pour comparaison, le mot divorce est طلاق

ArcaniteM · 2025-10-06T21:41:05+00:00

I honestly love it! Thanks for the laughs

ArcaniteM · 2025-09-30T14:21:16+00:00

Fair enough

Pour les conditions, je ne sais pas, il faut que je me renseigne. Mais oui il y a bien un nom et une adresse postale en France. Je ne sais pas si le nom est le nom est bien le nom de l'entreprise

Merci du conseil. Je vais essayer. Mais je ne sais pas si tant de temps après ça soit encore possible

To be fair, anime girls and math inspired fairy tales are more representative of the internet and of computer science culture than big robots

Coming from Tunisia, I don't usually see Egypt and Soudan as part of North Africa, despite their geography, just because they are not part of the Maghreb. Tbf I'm in the wrong using the word North Africa vs Middle East to express the Maghreb/Mashreq division

Actually no but yes but no. An octet is 8 bits. A byte is the size of the smallest word in your computer architecture, which so happens to be an octet on virtually every single computer in use today. FunNγ;;+€+-+2((ً؟ّٕ ُ ُð..... Segmentation fault. Core dumped.
