This study introduces a mutual selection model for weighted networks, accurately reproducing real-world network properties like power-law distributions and clustering coefficients.

Area of Science:

  • Network Science
  • Statistical Physics

Background:

  • Node connections in networks often stem from mutual affinity.
  • Existing models may not fully capture weighted network characteristics.

Purpose of the Study:

  • To propose a novel mutual selection model for characterizing weighted networks.
  • To explain the emergence of key network properties through mutual selection.

Main Methods:

  • Development of a general mutual selection mechanism.
  • Analysis of resulting degree, weight, and strength distributions.
  • Calculation of clustering coefficient, assortativity, and degree-strength correlations.

Main Results:

  • The model generates power-law distributions for degree, weight, and strength.

  • Key network metrics (C, r) emerge as functions of a single parameter.
  • Degree-dependent clustering and nearest neighbor degree reveal network hierarchies.

    • Conclusions:

    • The mutual selection model effectively describes weighted network architecture.
    • The model provides a unified explanation for observed network properties.
    • Empirical evidence supports the model's validity and predictive power.
