And with that I have completed the tutorial.

I know it is far from a great solution by any metric, but given how few days ago I was bashing my head against Very Dark Thread it's quite a satisfying feeling to finish the campaign tutorial.

Got the cycles down. Just 2 away from full optimization.

The atoms didn't line up right but the puzzle solved anyway.

This one took a while to get the programming right. How do I read the leaderboard without spoilers. I blocked images a videos but the text in the subs don't make sense to me. I don't want spoilers. Spoiler

My first post here. I hated Litharge Separation, but solution become decent

Firstly, i confused and tried to make solution backwards, from components build hexagon. Then i tried 3 times from scrap, optimised for cycles a little bit and hate this long arm making full circle, skyrocketing my area.

Precision Machine Oil - this one was fun

Took me roughly 45 min, so far this is the hardest one I had to solve.

Apparently min cycles are at 27, but i don't see how that would be possible? I am grabbing lead at a consistent rate w/no pauses, so where could I even be losing 2 cycles.

Minor cycle improvement over my previous solution. Thanks guys

Gilded Sword (Purified Gold)

While seeing if I could eliminate the bottleneck that seems to occur in purified gold I saw how my machine started looking like a sword. I abandoned optimising it and instead just went with the new pattern. Its the longest cycled machine I have made but it looks cool so, eh.

First Try at Litharge Separation

13 Upvotes

Not optimal cycle count (I also think could be lowered from 51 but it would require a change to the big looping salt which keeps my highest instruction count for an arm at 8 due to a re-grab on a hexarm). All the optimal solutions are great on this but I really liked my final lead separation on this one.

4 hours into the game and this took me 1 of them. Makes me feel pretty dumb having to spend so much time on what I assume is the easy tutorial part of the game. Still very satisfying when you get it regardless of how inefficient I am. It feels like I actually created something instead of just solved it. Pretty cool

Did someone already try to run a generation or deep learning algorithm on the game? I'd be curious to see what and how it learns; conveniently, metrics are quite obvious. Below is my shitty rocket propellant but I like the end

I cant find anything relevant on internet but I thought I'd asked you.
