Network-based cooperation with thresholds. Resource redistribution in kinship networks vs cooperation-epidemic coevolution with heterogeneity as leverage/weak-link.
When agents fall below a resource threshold, they solicit resources from connected neighbors based on relatedness. Redistribution creates feedback between kinship network structure and reproduction ability. This enables population survival at lower resource densities but increases network heterogeneity and local centralization.
view paper→Cooperation and disease transmission coevolve through network structure. Structural heterogeneity creates leverage points - highly connected hubs adopt protection due to amplified risk, catalyzing cooperation. Cost heterogeneity creates weakest links - low-risk individuals free-ride and act as disease reservoirs, undermining cooperation. Heterogeneity is double-edged: influence asymmetry facilitates cooperation, motivation asymmetry degrades it.
