報告摘要
IBP reduction might be a major bottleneck in Feynman integral computations due to its high time and memory demands. In this talk, I introduce NeatIBP 1.1, a package that efficiently generates compact IBP systems. It uses modern computational algebra techniques to greatly reduce the size of IBP systems. Compared to the traditional Laporta algorithm, it is much faster and more efficient. The new version adds a Kira interface for automated IBP reduction. It also employs the spanning cuts method and an optimized syzygy algorithm to boost performance in complicated cases. Therefore, NeatIBP 1.1 is expected to become a powerful tool for handling ever more complicated integral computations.
