# Toolbox-rs
A toolbox of basic data structures and algorithms. If you heard of OSRM, please draw your own conclusions. 😁
## Graph Plier
A tool to normalize graphs from various input formats into a normalized intermediate representation that is easily understood by the tool set.
## Chipper
A tool to bisect graphs in the DIMACS, (unweighted) METIS or DDSG format using an implementation of the Inertial Flow method. Example graphs can be downloaded on the website of the [9th DIMACS implemenation challenge](http://www.diag.uniroma1.it//challenge9/download.shtml). Chipper reproduces the runtime and quality numbers reported by [Schild and Sommer (2015)](http://sommer.jp/roadseparator.pdf). Currently, a balance factor of 0.25 is the default, and can be overridden via the command line.
## Scaffold
A tool to generate run-time data structures from pre-process graph. At this point it supports visualizing cells by their convex hulls. The result of this is stored in GeoJSON format which can be easily visualized, e.g. on [Kepler.gl](https://kepler.gl/demo).
```
$ cargo r --release --bin scaffold -- -p /path/to/USA-r20-m100.assignment.bin -c /path/to/USA-road-d.USA.co --convex-cells-geojson /path/to/bbox.geojson
```
## Complete usage work flow via cargo:
The complete work flow is as follows. First, the input data is converted into a normalized format, then the tools are run for processing.
Convert file to intermediate format:
```
$ cargo r --release --bin graph_plier -- -i dimacs -g /path/to/USA-road-d.USA.gr -c /path/to/USA-road-d.USA.co
```
Partition the graph recursively up to 30 times or until a cell has less than a hundred nodes:
```
$ cargo r --release --bin chipper -- -g /path/to/USA-road-d.USA.gr.toolbox -c /path/to/USA-road-d.USA.co.toolbox -o /path/to/result.txt -r30 -m100 -p /path/to/USA-r30-m100.assignment.bin
```
Generate GeoJSON file visualizing the cells:
```
$ cargo r --release --bin scaffold -- -c /path/to/USA-road-d.USA.co.toolbox -g /path/to/USA-road-d.USA.gr.toolbox -p /path/to/USA-r30-m100.assignment.bin --convex-cells-geojson /path/to/bbox.geojson
```
