To avoid duplicate calculations, we use incremental calculations of marginal gain strategies. After selecting the seed node, the overlapping impact is deleted and the impact of the rest of the nodes is recalculated. Finally, the seed nodes propagate the influence in the network in a specific diffusion model to maximize the influence range.
