This tutorial provides an introduction to finding and assembling pre-existing code to quickly create complex models. It uses code and data linked to the https://projectmercury.eu pages. We will create a Roman transport network by reusing existing code that draws on the open access ORBIS dataset (http://orbis.stanford.edu/), we will create alternative network structures by reusing existing code, and we will explore the impact these different network structures have in light of simple economic processes. This tutorial will reveal the importance of not reinventing the wheel, of searching for appropriate existing code and letting your model-building be inspired by others’ previous work.

A Python reimplementation of this module is available in python_implementation/, providing the same distance analysis and visualisation procedures as the original NetLogo model via the RomanTransportNetwork class.
Dependencies: Python >= 3.9, networkx >= 2.0, matplotlib >= 3.0, numpy >= 1.20
demonstration.ipynb: Jupyter Notebook demonstrating how to load the ORBIS network, run all four distance analyses, and produce all six visualisations replicating the NetLogo procedures.

| orbis.graphml | file | A .graphml file available for each implementation, consisting of nodes representing Roman settlements and junctions, and edges representing transport routes. From ORBIS https://purl.stanford.edu/mn425tz9757 |
| Name | Type | Description |
|---|---|---|
| Network topology | network | The set of nodes and links created using the ORBIS .graphml file, and corrected through the model's data-correction procedure. |
| distance distribution to Rome | frequency distribution | The frequency distribution of the distance from all nodes to Rome |
A draft model with some useful code for creating different network structures using the Netlogo NW extension: small-world, preferential attachment, circular, star, wheel, lattice, random, nearest neighbours.
