Abstract
We propose a paradigm for modeling real-world scale-free networks, where the integration of new nodes is driven by the combined attractiveness of degree and betweenness centralities, the competition of which (expressed by a parameter ) shapes the structure of the evolving network. We reveal the ability to seamlessly explore a vast landscape of scale-free networks, unlocking a class of complex networks that we call a stars-with-filament structure. Remarkably, the average degree of these networks grows like to some power, where is time and the average shortest path length grows logarithmically with the system size for intermediate values, offering fresh insights into the structural dynamics of scale-free systems. Our approach is backed by a robust mean-field theory, which nicely captures the dynamics of . We further unveil a rich, -dependent phase diagram, encompassing 47 real-world scale-free networks, shedding light on previously hidden patterns. This work opens avenues for understanding the universal properties of complex networks.
