Fitness centrality is a new method for identifying critical nodes in various networks, including cybersecurity and ecological conservation. It efficiently isolates key points that, if removed, would disrupt the network, outperforming existing methods by 15%. This computationally efficient approach requires only initial calculations, making it suitable for analyzing complex networks beyond economic analysis, addressing risks in supply chains, conservation, and infrastructure.
