## Running the solutions
For convenience, the project has a `setup.py` that specifies a package, for local path resolving.
This can be installed locally in the python (virtual)environment by using:
```bash
pip install -e .
```
Problems can be run by running the file, most should have a main method with some sample input, e.g. :
```bash
python p16_20.py
```
## Some highlights
### Langton's ant (Chapter 16, Problem 22)
An interesting example of emergent patterns from simple rules. Raise the number of iterations in the code to see more of the "highway" form.
For more information, check the [wikipedia link](https://en.wikipedia.org/wiki/Langton%27s_ant).
### Tree visualising in VS Code
This requires graphviz to be installed locally and the extension added to VS Code.
