We introduce a local strategy for building scale-free networks with tunable degree distributions. This method allows precise control over small-degree behavior while maintaining the power-law tail characteristic of complex networks.

Area of Science:

  • Network Science
  • Statistical Physics
  • Complex Systems

Background:

  • Scale-free networks exhibit power-law degree distributions, crucial for understanding network robustness and function.
  • Existing network construction methods often lack flexibility in controlling specific degree distributions, particularly at small degrees.

Purpose of the Study:

  • To propose a novel, local strategy for constructing scale-free networks with arbitrary degree distributions.
  • To enable fine-tuning of network properties at small degrees while preserving the scale-free characteristic at large degrees.

Main Methods:

  • Adaptation of the Krapivsky and Redner redirection method for network growth.
  • Incorporation of external parameters to control local network structure and degree distribution.

  • A local attachment strategy requiring only immediate neighborhood information.

    • Main Results:

    • The proposed method successfully constructs scale-free networks with user-defined degree distributions.
    • External parameters effectively tune network behavior at small degrees, complementing the power-law tail at large degrees.
    • The target degree distribution is maintained throughout network evolution.

    Conclusions:

    • This local strategy offers a flexible and efficient approach to generating complex networks with desired properties.
    • The method's locality makes it computationally advantageous for large-scale network construction.
    • The ability to control arbitrary degree distributions opens new avenues for network design and analysis.
