Sustainable Agriculture in Egyptpole expansions for the inverse square law. It can be considered as a multipole-based variant of Barnes-Hut algorithm . The key idea here is the representation of forces (gravitational or electrostatic) through a multipole series by using the relationship between ultraspherical and Legendre polyn责怪 发表于 2025-4-1 10:34:53
