The research area of influence maximization and matroid intersection is experiencing significant advancements, particularly in the development of efficient and scalable algorithms. Recent studies have focused on leveraging distributed computing resources, such as GPUs, to enhance the speed and accuracy of influence maximization algorithms. Innovations like DiFuseR demonstrate substantial speedups in multi-GPU environments, addressing the computational challenges inherent in large-scale network simulations. Additionally, novel approximation techniques for spanning centrality and matroid intersection are being introduced, which significantly reduce computational complexity without compromising on accuracy. These methods often employ advanced sampling and parallelization strategies to achieve remarkable performance improvements. Notably, deterministic algorithms are also being refined to provide near-optimal solutions with fewer queries, making them more practical for real-world applications. Overall, the field is moving towards more efficient, scalable, and deterministic solutions that can handle the complexities of large networks and multiple seed set requirements.

Noteworthy papers include DiFuseR, which showcases a significant speedup in influence maximization using distributed GPUs, and the novel hash-based sampling method for approximating spanning centrality, which demonstrates substantial improvements in execution time through clustering random walks into Bouquets.
