Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Abstract For N-body simulations, event-list is used to store timing information about potential interactions between pairs of N particles. We reported that the number of entry of the list can be reduced much smaller than the number of potential interactions and the reduction improves performance of simulation. Small list can be handled easily using array structure. In this article, we reimplement the method with an array, instead of complex tree, and find that the optimal number of entry is about N. W...
