Our coevolving threshold model incorporates two mechanisms: the threshold mechanism for the spreading of a minority state such as a new opinion, idea, or innovation and the network plasticity, implemented as the rewiring of links to cut the connections between nodes in different states. Using numerical simulations and a mean-field theoretical analysis, we demonstrate that the coevolutionary dynamics can significantly affect the cascade dynamics. The domain of parameters, i.e., the threshold and mean degree, for which global cascades occur shrinks with an increasing network plasticity, indicating that the rewiring process suppresses the onset of global cascades. We also found that during evolution, non-adopting nodes form denser connections, resulting in a wider degree distribution and a non-monotonous dependence of cascades sizes on plasticity. | Descripción: | 8 pages, 6 figures. | Versión del editor: | https://doi.org/10.3390/e25060929 | URI: | http://hdl.handle.net/10261/352196 | DOI: | 10.3390/e25060929 | E-ISSN: | 1099-4300 | Referencias: | Min, Byungjoon; San Miguel, Maxi; 2023; Threshold cascade dynamics on coevolving networks [Preprint]; arXiv; Version 2; https://doi.org/10.48550/arXiv.2305.13965 |
