From: The evolutionary extortion game of multiple groups in hypernetworks

Hyperdegree distribution of nodes is shown in the double logarithmic coordinates. The horizontal coordinate is hyperdegree of nodes, and the vertical coordinate is the frequencies of hyperdegree of nodes occurrence. This figure indicates that nodes with few number of hyperdegree have high frequency, while nodes with more number of hyperdegree have low frequency. The results show that the hypernetwork structure in our model is a scale-free hypernetwork and has the property of the “Matthew effect”.
