# Advent of Code 2018
|
|

|
|
|
|
Once again, I will be attempting to complete the challenges in Rust.
|
|
However, this this I will be focussing on having idiomatic code and
|
|
having everything in a single executable.
|
|
|
|
To run day 1: `cargo run -- 1`. Other options can be seen with the
|
|
`--help` flag. The program will by default read its input from stdin.
|
|
|
|
## Correctness
|
|
|
|
All of this year's solution implementations have some semblance of unit
|
|
tests, all coming from the examples given in the problem statement.
|
|
These tests are checked by travis (if you haven't noticed the shiny
|
|
button above) on stable, beta and nightly Rust, as well as the version
|
|
of Rust that Ubuntu Xenial ships.
|
|
|
|
## Simulations
|
|
|
|
This year's edition is very simulation-heavy. Thus, code written for
|
|
those days tends to be very long. To illustrate this, I have created the
|
|
graph below. Can you guess which days had a large simulation?
|
|
|
|
|
|
|
|
The code to produce this graph is included in the `other` directory, and
|
|
should be compatible with most peoples repo set-ups, so you can share
|
|
your pain. If it is not, please let me know.
|
|
|
|
## Performance
|
|
|
|
I benchmarked the performance of my implementations on stable rust
|
|
(1.31.1 at the time of writing). The logarithmic runtime graph looks as
|
|
follows:
