SECIHURD Model - ReproductionNbSim

A C++ and Python-based simulation tool developed for a seminar on the Mathematical Modelling of Infectious Diseases. This project reproduces the SEIR-extended compartmental model (SECIHURD) used to analyze the COVID-19 epidemic in Italy.

Reference Paper: Modeling the COVID-19 epidemic in Italy

Important

This version currently supports Windows only due to specific filesystem and DLL handling.

🚀 Getting Started

Prerequisites

• Visual Studio Community (with C++ Desktop Development)
• CMake (version 3.10+)
• Python 3.x (for fitting and visualization)

Build Instructions

1. Build Libraries: In each subfolder within ./libs/ (e.g., RungeKuttaLib):
   • Create a build folder.
   • Run cmake -S .. -B . inside that folder.
   • Open the generated .sln file in Visual Studio and build the solution.
2. Build Main Model:
   • Create a build folder in the root ReproductionNbSim directory.
   • Run cmake -S .. -B . inside.
   • Open the .sln and build the project.
3. Link Dependencies:
   • Copy the .dll files generated in the library build folders into ReproductionNbSim/build/Debug.
