NEXUS is a crisis response simulation system that models how populations share information during emergencies. The project analyzes the propagation of rumors versus accurate information and studies collective decision-making under stress conditions.

## Core Problem
Understanding how information flows through society during disasters, identifying bottlenecks, and optimizing communication strategies to improve disaster response outcomes.

## Novel Approach: Beyond Traditional RAG

Instead of conventional Retrieval-Augmented Generation (RAG), NEXUS implements:

### 1. **Semantic Propagation Graphs**

### 2. **Attention-Based Selective Broadcasting**

### 3. **Information Propagation Methods**
