Code for Multidimensional Opinion Dynamics Model with Higher-Order Structure

This repository stores the code for our paper entitled "Amplified topic coupling and polarization by higher-order interactions in multidimensional opinion dynamics". It contains the main scripts used for the numerical simulations, empirical validation, and stance-based analyses reported in the manuscript. The empirical Reddit data are not included in this repository. They can be collected from the Arctic Shift Reddit dataset interface: https://arctic-shift.photon-reddit.com/download-tool.
