# INF562 - OCM Problem
Author: Thibaut de Saivre
A solver for the One-sided crossing minimization problem.
See [the PDF report here](./report/ocm-report.pdf).
See some [python benchmarks here](./analytics.ipynb).
The challenge outputs are in the [output](./output) folder.
## Quickstart
### CLI
Run the CLI solver with the following command:
```bash
cargo run --bin ocm-cli -- -a median -v datasets/tiny/complete_4_5.gr
```
### GTK
A GTK GUI is available. However, it requires GTK4. Installation instructions are available [here](https://gtk-rs.org/gtk4-rs/stable/latest/book/installation.html).
The [Rust book of GTK4](https://gtk-rs.org/gtk4-rs/stable/latest/book).
You can then check the gtk version on your machine:
```bash
pkg-config --modversion gtk4
```
Then run the GUI with:
```bash
cargo run --release --bin ocm-gtk -- -a median datasets/tiny/complete_4_5.gr
```
Run the CLI solver for large graphs and time it with:
```bash
cargo run --release --bin ocm-cli -- -a median -v datasets/large/25.gr
```
## Project structure
This project uses `cargo workspaces`.
```bash
├── datasets # Graph datasets for testing
│ ├── large
│ ├── medium
│ └── tiny
├── ocm-cli # CLI program for solving the OCM problem
├── ocm-gtk # GTK GUI for solving the OCM problem
├── ocm-parser # Graph dataset parser
├── ocm-plotter # Plotting functions
├── ocm-solver # Implementation logic
├── output # Challenge outputs
└── report # LateX report
```
## Benchmarks
Various benchmarks are available using tests.
- `line_sweep_crossings` benchmarked over all datasets, in the [`crossings.rs`](ocm-solver/src/crossings.rs) file.
ISSUE: the benchmarks run very long for 2 of the large dataset files. You can interrupt the benchmark early, as the results are progressively written to the [`crossings_benchmark.csv`](./crossings_benchmark.csv) file.
Run them with the following command:
```bash
cargo test -- --nocapture # Do not capture stdout so that we can see progress indicators in stdout
```
