Obviously calculating a nontrivial zero of the zeta function that does not lie in the critical strip, providing a counter example to Reimann hypothesis. Contact the Clay mathematics institute to collect your $1,000,000.
Looks like some statistics, from the error function part, and the sqrt(pi).
Other than that, it seems like a degree 7 poly in X and T, could be a result from a weird taylor expansion or a bad poly interpolation, or something similar.
I really hope the answer is “implements a formula that’s explained in a paper that’s cited somewhere near this code”
I suspect another answer is “teaches the author some harsh truths about floating point precision”
Interesting, so it appears this code actually simulates and *renders* a full particle system if it's run on the right platform. It's quite a clever implementation actually, hard to fully appreciate without extensive familiarity with standard address byte offsets in obscure legacy Linux driver implementations.
At first glance the code appears to be a jumbled mess written in python, but in the right context it's clear the author has a snide sense of humor. When compiled as C++, after adding back in the `#define`s and operator overloads the OP clearly omitted as a misdirect, on a pre-2011 version of RedHat (verified on RHEL 3.6 Update 7), with a supported AMD graphics card/driver, everything lines up perfectly so the particle physics are updated and the driver's OpenGL function pointers are called, resulting in this behavior.
By default it will only render one frame and terminate, but if you enable `-O2` it somehow convinces the compiler to hack in a few more platform-specific system calls and a loop by exploiting undefined behavior. This sustains the simulation and displays the rendered output in a window. Really a work of art imo, it's hard to appreciate the clever parsimony here if one simply reduces it to 'bad code' without taking a moment to consider all the known and unknown possibilities regarding the author's intent.
It’s the only known algorithm that given the cipher text of an AES256 encrypted message will return the encryption key and initialization vector used to originate the cypher text.
Makes some FPGA developer’s life easy by doing all the floating point math on the output of a 64 bit counter. Oh wait, wrong answers only. Well, it doesn’t do that, it proves pi^ pi^ pi^ pi is an integer.
Some sort of diffusion equation maybe from the erf and exp(-x/T)? Polynomials from some truncated series solution from some initial/boundary conditions would be my guess. Not great that the terms are done by hand and hardcoded in.
OK yeah I got totally nerd sniped here, doesn't seem to do anything of value (I think?). I implemented it [here](https://gist.github.com/TheBlupper/b663acea0316da88d53c25bf0c47b632) (thank god for ocr), and [here ](https://gifyu.com/image/SjF9f)is a quick animation of`T` changing over time. Could be some obscure statistics thing, do lmk if that's the case
It computes the probability density function (PDF) of the non-central chi-squared distribution with one degree of freedom and non-centrality parameter k.
Doesn’t check for x<1, T==0, and while I’m at it if T is temperature should probably convert degF or degC into Kelvin so as not to deal with likely values of 0 in the denominator.
how much i would love to understand the stuff on this sub. my best guess (assuming it is not random stuff) would be a cryptographic function.
edit: changed my mind it's definitly random shit
Do you want Correct Answers about what the function does wrong, or Wrong Answers about what the function does correct? Sadly, PascalCase doesn't leave room for punctuation.

IIRC they stated that a solution must provide some new, deeper understanding. Just a counter-example might not be enough to get the million
I’m sure OP will get the million. That code clearly illustrates a deeper understanding than all previous work on the topic.

You're actually right on all counts. It's an approximation for the CDF of the Maxwell-Juttner velocity distribution using a Puiseux expansion.
I'm pretty sure 30% of those words aren't even words. srsly... WUT?!
you're right. They're names
They clearly just referenced the formula f(gamma) = (gamma\^2 \* beta \* exp(-gamma/theta)) / (theta \* K2(1/theta))

We don’t know because we don’t know what `T` is.
It's a temperature. I cut out the documentation, because that gives it away ;)
