ABM Rome Simulation v1.0.0

v1.0.0 — Rise & Collapse of Maritime Empires

This release introduces an agent-based NetLogo model simulating the emergence, dominance, and collapse of maritime empires through trade, geography, and political instability.

Features

• A* maritime pathfinding for realistic sea routes around continents
• Economic feedback loops producing emergent inequality (“rich get richer”)
• Dynamic Trade → War transition controlled by a global Imperial Stability parameter
• Crisis mechanic triggering systemic collapse and total war
• Real-time inequality metrics, including Lorenz Curve and Gini coefficient
• Performance optimizations enabling long-run (multi-era) simulations

Model Behavior

• High stability → expanding trade networks with growing inequality
• Low stability → rapid network breakdown and imperial collapse
• End states consistently converge toward monopoly or duopoly dominance

Validation

The model was verified through isolated navigation, economic, conflict, and data-visualization tests to ensure robust and interpretable outcomes.
