the simulation in question:

for (int i = 0; i < 80000; i++) {
   if (rand() % 2 == 0) {
      printf("Kamala wins\n");
   }
   else {
      printf("Trump wins\n");
   }
}

This is much cleaner than mine that I did in python.

thanks. Nate Silver paid me $50k to write this

[-] [email protected] 13 points 8 months ago

could you please input that into chatgpt so it will give me a summary of the code output? I'm a busy data driven guy so I don't have time for the details. however, I do have time for this post

[-] [email protected] 12 points 8 months ago

Hey! I understood that! That Python class must've taught me something after all.

[-] [email protected] 8 points 8 months ago* (last edited 8 months ago)

Seems lots of unnecessary mods tbh,

S=0

for i in 1:80000

S+=rand()

end

ceil(S)

Modding by 2 is just a bitwise operation tho

[-] [email protected] 2 points 8 months ago* (last edited 8 months ago)

Gotta dump results in some accumulate tho, and if then logic might be eh (although with branch prediction it might be auto 2 threads actually soviet-hmm or similar utilization at least)

[-] [email protected] 2 points 8 months ago

A reasonable compiler could optimize this into a bitwise AND, load the pointer to the appropriate string constant into a register branchlessly using a lookup table or cmov instruction, and then execute a single call to printf.

[-] [email protected] 1 points 8 months ago* (last edited 8 months ago)

I mean if I want to know the precise number, like 40012 or whatever. Obviously single call is fast, but printf of 40000 strings single strings is meh. I mean in my variant I don’t run comparison, even bitwise, just 80000 rand and sum, single ceil and print

huh, the sync for Lemmy code block renderer doesn't show the \ even within the code block 👁️👁️

how the fuck does a "simulation" like this even work? so insane

[-] [email protected] 52 points 8 months ago

Take polling data then randomly roll for some error within the margin of error for each state. Then adjust based on bias. Do this n times and get your prediction.

[-] [email protected] 28 points 8 months ago

Is there a point to this? From the tweet it doesn't give new information. It just reaffirms that three contest will be close which everyone knew.

[-] [email protected] 33 points 8 months ago

They didn't get a certain answer so it was useless this time, but if it had turned out that somehow one candidate won a supermajority of simulations then you got useful information. Can't know unless you ask.

[-] [email protected] 26 points 8 months ago

There is utility in some cases; there's correlations between polling and areas, and the electoral college makes it all complicated (by design)

But, like, here? No, no practical difference between any of the 'models' all showing some variation of 'its a toss up'

[-] [email protected] 13 points 8 months ago

stochastic modeling is the key word for this type of modeling if you actually care. that kind of thing is used for all kinds of stuff - weather, climate, ecology, river flows, economics

"We flipped a coin 80,000 times and it landed on Heads 40,012 times"

[-] [email protected] 34 points 8 months ago

I ran 80,000 simulations of me taking a poop

In 40,000 of them, shit ran down my ballsack and then I had shit on my balls.

[-] [email protected] 11 points 8 months ago

In 32 of them, I sneezed in the middle of a stream of diarrhea and covered the entire backside of the toilet.

homie's monte carlo analysis probably took like 9 seconds to run

[-] [email protected] 23 points 8 months ago

Based on my coworker's workflow, the simulations took up all computing resources they had all day, and the confidence interval was like 0.1% tighter.

[-] [email protected] 29 points 8 months ago

For anyone curious, this means Harris won 50.015% of the time

Truly an earth-shattering margin

[-] [email protected] 28 points 8 months ago

I flippee a coin and it landed on heads 40,012 times, here's how Harris can still win

We're living in a Nate Silver simulation right now. :morpheus:

We surveyed the Adeptus Astra Telepathica and every seer came back with the same answer: landslide victory for the Emperor of Mankind!

Praise be the God Emperor!

[-] [email protected] 4 points 8 months ago

Of course you have to vote for the God Emperor! Sure he's genociding everyone who isn't human (and quite a few people that are but shush) but if you don't vote for him then Horus will win! And Horus is going to be so much worse, he'll implement project 025.M42 and abolish the planetary governors! The God Emperor can win if you vote for him!

(I may have mixed my 40k and 30k for the bit, shhh)

Nate Silver thinks he’s Dr. Strange

Kamala Harris IS The Deadliest Warrior.

[-] [email protected] 13 points 8 months ago

I was actually surprised that that company's 40k civ game was actually pretty fun.

No idea what their "simulations" consisted of in deadliest warrior though, biggest chunk head show

[-] [email protected] 13 points 8 months ago
[-] [email protected] 12 points 8 months ago

He just like dr strange fr fr

[-] [email protected] 10 points 8 months ago

Can someone explain to me why the hell he’s ever needed a monte-carlo analysis? The margin of error is gaussian, and it’s not like it’s running up against zero bounds when it’s 50/50, so why isn’t it just a linear equation?

It’s just a linear equation, right? He does a monte-carlo so he can brag about running 80,000 simulations, not for any good reason, right?

[-] [email protected] 1 points 8 months ago

I presume he is running a monte carlo analysis to account for the electoral college, which makes the equations non-linear.

[-] [email protected] 10 points 8 months ago

After viewing thousands of possible futures, the only timelines where Kamala wins are ones where she hands Dick Cheney an Infinity Cabinet Post and lets him turn half the Democrats into dust.
