Really pleased with how ROBODOJO ended up, and I'm loving the different bot builds people are creating.

I've probably missed a fancy coded solution for part two of today's #AdventOfCode but went for the eyeball approach instead. Three of the swaps were fairly easy to spot, but one was particularly elusive (see attached). One day left!

Today's #AdventOfCode initially looked like it was gearing up to be a hardcore graph problem, but was ultimately solvable in <0.5s with a couple of for loops and some basic optimisations. A nice start to the day!

Much nicer #AdventOfCode today - just took some careful reading. This also marks the further I've made it through an AoC. Hopefully the next few days don't get too busy!

#AdventOfCode was definitely a challenge today, as I ended up with several solutions that worked for the test cases but not the real input.
For part 2, caching helped a bit but ultimately I had to ditch the full sequences and go for counts - similar to Day 19.

Spent a bunch of time faffing around with skip visualisations today, only to realise that the paths weren't actually needed for part 2... At least debugging part one visually was enjoyable!

Initially implemented a trie-based approach that tracked all sequences for today's #AdventOfCode. But then had to simplify this to a mix of str.startswith and counts to support caching for part two.

Fairly straight-forward application of Dijkstra + binary search to solve #AdventOfCode today.
I was expecting part 2 to involve placing bytes with each step, but off-by-one errors were the real villain.

Pretty intense #AdventOfCode today, I ended up down several optimisation rabbit holes as I tried to fully understand and reverse engineer the algorithm. Only to be hit with sudden realisation when I spotted the blocks of eight in the iterative output!

A classic Dijkstra-based solution for today's #AdventOfCode - and a great opportunity to experiment with emoji for my debug visuals.

Spent too long wrestling with numpy.linalg.solve and floating points only to stumble upon Cramer's rule and is_integer. Definitely a learning day!

Day 12 was a nice little island finding style challenge. My solution is pretty fast, but probably not optimal.
I also ended up creating a whole bunch of test inputs as my optimisation attempts only created weird edge cases!

Initially thought today's #AdventOfCode might be about big number multiplication, but it was really a "memoize what matters" problem.
In the end, I wrote both slow (good for part one, keeps the sequence) and fast (vital for part two, just counts the stones) approaches.

Quite a nice challenge for today's #AdventOfCode, helped by me inadvertently writing a solution for part 2 after misreading part 1!
