my rust solution - runs in ~650ms. All it does is explore all possible move sequences that obey game rules. Ordered by increasing total cost.

Thanks! In the meantime, I was able to slash the runtime in half by using a faster hash (fxhash) for the cache.

[2021] My aim is for all of this years solutions to be sub 1s in total. So far so good.
Same here $ cargo run --release -- --skip-output Finished release [optimized + debuginfo] target(s) in 0.02s Running target/release/aoc21 --skip-output Day 01 took 10.008Β΅s to compute (with i/o: 146.55Β΅s) Day 02 took 9.355Β΅s to compute (with i/o: 87.184Β΅s) Day 03 took 82.134Β΅s to compute (with i/o: 155.095Β΅s) Day 04 took 52.834Β΅s to compute (with i/o: 240.457Β΅s) Day 05 took 673.742Β΅s to compute (with i/o: 776.801Β΅s) Day 06 took 1.306Β΅s to compute (with i/o: 7.122Β΅s) Day 07 took 33.248Β΅s to compute (with i/o: 55.737Β΅s) Day 08 took 984.71Β΅s to compute (with i/o: 1.00838ms) Day 09 took 883.739Β΅s to compute (with i/o: 922.913Β΅s) Day 10 took 19.062Β΅s to compute (with i/o: 126.791Β΅s) Day 11 took 398.191Β΅s to compute (with i/o: 400.35Β΅s)

Advent of Code day 12 advise
I was having a hard time figuring out day 12 of Advent of Code. In the end I gave up and went looking for some solutions. I came across this one and this one. However, I didn't quite understand what they did.

F# solution in Jupyter Notebook. Got some help from this thread.

F# solution in Jupyter Notebook. Part 1 takes 500ms but Part 2 takes 24s. Any suggestions on where performance could be improved would be appreciated!

F# solution in Jupyter Notebook. Thank God for the Haskell programmers! I would not have been able to solve this without peeking at their some of their code. Parsing the input string was just the first of the challenges! I envy those dynamic programming languages with an eval function.

F# solution with Jupyter Notebook. Brute force. I actually solved Part 2 before solving Part 1, unknowingly.

F# with Jupyter Notebook. Learned how to use recursive types today! Half-way through the problem I was starting to wonder whether BITS was going to be the new IntCode.

[2021 Day 15 (Part 1 & 2)][F#] Why is my implementation of Dijkstraβs Algorithm so slow?
So this year I'm learning F# and functional programming. I could not figure out a immutable solution. So I went with an imperative, mutable solution and did pretty much a straight port from Red Blob Games including using a PriorityQueue.

F# with Jupyter Notebook. Slow but works. I'll probably come back to this day and optimize the solution.

-π- 2021 Day 11 Solutions -π-
F# in Jupyter Notebook. Decided to go with an infinite sequence (generator pattern) for the steps. This made Part 2 a breeze!
