I'm going to go out on a limb and suggest that number is not actually employee income tax, even though the report seems to suggest the same. Employee income tax is an expense of the employee, not the employer. If it is income tax withholding, it's way too small for $150k+ of employee comp, which is another reason I don't think it's that. Instead, I expect this tax line item to be primarily the employer share of FICA tax, which is typically considered a payroll tax instead of an income tax.

which would take longer than the heat death of the universe to find the global maxima

Sure, if you're using brute force, instead of a polynomial time algorithm.

It doesn't matter what algorithm you use, finding the absolute best solution and proving it is impossible.

Hard disagree: https://en.wikipedia.org/wiki/Hungarian_algorithm

Linear Assignment seems a very strange choice to illustrate the utility of meta-heuristics, when that particular problem has a polynomial-time solution algorithm that has been known for 70 years.

Watched your Linear Assignment video, and the whole time I'm thinking why would one ever contemplate a meta-heuristic for Linear Assignment when Hungarian/Munkres runs in polynomial time? I think I must be missing some context.

Hmmm. The original, in fact, does NOT have the 0x0a at the end of the file; however, in process of deleting first part of file up through and including "1.#####", my linux command line tools (or vim?) added one there (unbeknownst to me at the time). I proceeded to solve first puzzle with the 0x0a there at the end in the head-shortened ciphertext, and I got readable plaintext, but my sha256sum does not match yours. If I remove the 0x0a, I get neither readable plaintext nor a matching sha256sum.

(btw, love this project, thanks for sharing it)

I had a very similar problem this week, trying to encode 5**13 states in a 32-bit int. Should be doable with this. What is this encoding called? I haven't seen it before.

Epic comment and diagram, thanks. From this, how can we calculate bearing and distance from one of our locations to the source? Edit: I see that we can use multilateration suggested by parent-sibling comment if we just had distance to source (ie radius of unique tangent circle).
