In my experience plotter art is a fantastic creative outlet for programmers/people with math backgrounds, especially if your day job doesn't produce anything physical in the real world. Shameless self-plug but I recently animated

Breaking old seeds is probably not too big a deal since the game is currently in early access, and the biweekly patches mean that seeds are already pretty inconsistent. For example, adding new cards/relics/combats to the pool thro

Random thing I ran into while trying to seed search for a challenge run, but since the seed is passed through a 32-bit hash function it means there's effectively only 4 billion seeds (as opposed to the first game, which had 64 bit seed

The trick for Scenarios 2 and 3 is that most of the constraints don't end up being bottlenecks. For example in Scenario 2, well-connected pretty much always gets satisfied while doing the other constraints, so the DP table only needs 4

The tricky thing is the code for making decisions runs locally on the contestants machine, so the first time they submit they can record the sequence locally and compute the best set of actions for the next time they submit. Even if the seq

Nice to see another participant's thinking process for the puzzles! I ended up getting 5th place using dynamic programming for all of the scenarios, but I'm under the impression that almost everybody in the top 20 had almost equal

I could see it being handy to estimate probability where each word is to better inform each guess. The tricky thing is I'm not sure if each run of wave function collapse (with randomness injected) would be an accurate sampling method f

Good catch! I didn't know about this, I'll update the footnote. Anecdotally everyone I know was very surprised by KEFIR the other day.

Yeah, I really like the sorting formulation! I didn't notice until after I'd written out the intended solution, but it's basically radix sort going from most significant to least significant bit.

Before publishing I found this while trying to see if there was a already a riddle like it out there (closest I could find was the 1000 barrels of wine riddle mentioned at the beginning): https://puzzles.nigelcoldwell.co.uk/

I originally set it up like that, but felt having to explain that you need to subtract 2000 before doing the binary conversion was unnecessary and kind of distracting

That's really cool! I tried to get something to work last week on pen and paper but couldn't get anything to stick. Is there a strategy you used or did you just go by feel? Edit: just noticed how you encoded a flip (AB <-->

Yeah, it's in the last image and in the thumbnail at very top (which I realize now is really hard to spot on mobile), intentionally not in the spotlight to leave space for the twist at the end. https://chriskw.xyz/image

I'm by no means a parenting expert, but my answer would be anything related to something they feel passion or wonder for in the moment. I snuck in a paragraph near the end about burnout. At the root of the problem for me was that I los

Thanks Cliff, it means a ton coming from you! The videos from you and all the other folks on Numberphile always inspired me to see the beauty in math growing up :)

The post presents it a bit out of order, but it was mostly from realizing at some point that the way the fractal grows by a factor of 5, base 5 number systems, and the "spiral" mentioned in the post can all fit together. I also th

I did something similar once (with a bit of a twist) for my bio when I was a TA in college: "Hi! I’m a senior studying CS. My hobbies include making semantic paradoxes and my bio includes eight a’s, seventeen e’s, fourteen i’s, eight

I did something similar to option 3 to make the builtin numeric types "callable", since the dunder __call__ methods can't be overwritten for builtins. For example, in regular arithmetic notation, something like 6(7+8) could b
