I’ve been thinking about this for days.

@mhoye @jonathankoren are you sure about the more reliable the larger input? Prime number are weird

[et@mastodon.bayern]

@mhoye @i0null @jonathankoren How can I unsee this?

[finestructure@mastodon.social]

@mhoye @jonathankoren It might be sentient

[i0null@infosec.exchange]

@et @mhoye @jonathankoren
bool mark_as_unread() {
return true;
}

@mhoye Algorithms like this are used as a pre-prime testing before you do the actual prime testing that requires CPU heavy computation.

@mhoye @jonathankoren Snort!

@jonathankoren
It is one of the best one-class classifier I've ever seen. Extremely efficient and the computational time doesn't grow the larger the input gets.

@mhoye @Nephele @jonathankoren
That's prime crime

[stylus@social.afront.org]

@mhoye @silicatefondue @jonathankoren this class of algorithm is called the stopped clock algorithm. It joins the previously identified Monte Carlo and las Vegas algorithms.

@mhoye @jonathankoren If you change that to:
return !(x&1);
You have improved the probability quite a lot and still fast and won't get optimized away.

[mjdxp@labyrinth.zone]

@mhoye @jonathankoren amazing, we've discovered prime numbers past 2

[mschomm@bonn.social]

@jonathankoren Is there a use case for Bogosort?

[mhoye@cosocial.ca]

@mjdxp @jonathankoren This changes everything!

[mhoye@cosocial.ca]

@finestructure @jonathankoren oh shit you’re right

[yesbait@bsd.network]

@mhoye @jonathankoren can absolutely relate. Constantly trying convince my quantitative colleagues that discrete maths is different from their stochastic and AI based reasoning.

[tygerkrash@mastodon.ie]

@mhoye @jonathankoren thats fantastic.

[thelancashireman@hostux.social]

@mhoye @jonathankoren

Reminds me of another ...

float sin(float x) { return x; }

is remarkably accurate for a large proportion of the possible input values.

@mhoye @jonathankoren
And it’s O(1) too!
