On Quantitatively Measuring Controllability of Complex Networks

TL;DR

This paper introduces a quantitative index to measure the controllability of complex networks and analyzes its effectiveness across different network topologies like random, small-world, and scale-free networks.

Contribution

It proposes a new controllability index and evaluates its applicability to various complex network models, providing a quantitative assessment method.

Findings

The index effectively measures controllability across different network types.

Controllability varies significantly with network topology.

Empirical analysis demonstrates the index's usefulness in network control assessment.

Abstract

This letter deals with the controllability issue of complex networks. An index is chosen to quantitatively measure the extent of controllability of given network. The effect of this index is analyzed based on empirical studies on various classes of network topologies, such as random network, small-world network, and scale-free network.
