We describe two new algorithms for N-body simulation which are generalisations of the Barnes-Hut algorithm capable of modelling interactions between the internal nodes of the oct-tree data structure representing a 3-dimensional space of particles.The two algorithms,Cell Propagation and Mass Partition,...
Barnes-Hut optimization highlighted as points converge to their t-SNE positions Ten years ago, while writing aphysics engine(opens in new tab), I learned about theBarnes-Hut algorithm(opens in new tab)for the gravitationaln-body problem(opens in new tab). Normally, computing the Newtonian grav...
