c554811fda
Clean up day 16 and 19.
...
Day 16 and 19 share the same CPU and now they actually share the same
code for it.
2018-12-19 07:53:09 +01:00
cb99849143
Implement day 19.
...
With nice hotspot optimization for part 2.
2018-12-19 07:12:46 +01:00
1e26ad1168
Correctness.
...
From::from may never fail, so I added an invalid state.

Curiously, it reminds me of some other day involving plants.
2018-12-18 12:03:05 +01:00
f23624c456
Fix all clippy warnings.
2018-12-17 12:26:31 +01:00
851868bed4
Even more clean up.
...
Removed duplicated code in the descend stage and moved it to different
functions. Also, range finders are no longer technically infinite, but
are assumed to be.
2018-12-17 11:45:23 +01:00

Clean up.

Fix day 15 part 1.
2018-12-15 21:12:58 +01:00
ae51e3c114
Clean up and simplify.
...
The idea is that this makes it easier to debug. I'm not sure it does
yet.
2018-12-15 19:12:33 +01:00
44e5c38268
Attempt to fix Ubuntu incompatibility.

Reuse manhattan implementation from common.
2018-12-15 18:08:42 +01:00
069e381aeb
Partial solution for day 15 part 1.
...
Partial in the sense that it doesn't actually work for my input, only
for the samples.
2018-12-15 18:02:16 +01:00
bcccc85073
Reimplement day 14 with infinite streams.
2018-12-14 14:48:53 +01:00

Make day 12 even more rusty.
2018-12-13 14:55:30 +01:00

Deduplicate day 12.
2018-12-13 14:47:00 +01:00
91f0ec55f1
Slightly cleaned up by using structs.
2018-12-13 11:44:18 +01:00
e6c8c6b100
Implement a very ugly part 2.
2018-12-13 11:24:03 +01:00
973c9ed63b
Add a part1 implementation and wrong part2.
2018-12-13 10:52:32 +01:00
e22f934ea6
Remove code duplication.
2018-12-12 16:12:26 +01:00

Preallocate correct state length.
2018-12-12 13:08:35 +01:00
247613555b
Implement day 12 part 2.
...
This in no way should work, but it does, at least for my input.
2018-12-12 12:44:27 +01:00
fd3e509841
Implement part 1 of day 12.
...
Part two is going to take 31 hours of computation, so I might need to
improve that.
2018-12-12 11:30:45 +01:00
b245e0911d
Implement the summed-area-table algorithm.
...
Which is somewhat awkward for the edge cases (that are not in my input!)
but is really fast anyway.
2018-12-11 18:14:15 +01:00
4b8255728c
Remove an invalid optimization.
2018-12-11 15:49:39 +01:00

Implement day 11 part 1.
2018-12-11 10:31:23 +01:00
eaf1156ae0
Refactor for autovectorization.
...
By storing x/y as a vector of ints instead of a vector of tuples, the
compiler recognizes it for what it is: a huge vector multiplication. Now
the compiler emits AVX2 instructions.
2018-12-10 17:13:10 +01:00
c3480482f2
Implement an estimator function for day 10.
...
This bumps the speed tenfold.
2018-12-10 14:17:57 +01:00

...
This implementation is stupid but it works.

Pre-allocate correct size.
2018-12-09 17:47:22 +01:00

Prepare future scaffolding.
...
Also reformat the code, but that is nothing significant.
2018-12-09 13:02:54 +01:00
9b04e3b2c9
Implement day 9 part 2.
...
Linked lists in rust are a pain, but we got there.
2018-12-09 10:57:47 +01:00

Move get_impl to crate.
