Virtual memory is conceptually simple but potentially devastating to performance. Every memory access must go through segmentation (add segment base, check limit) and then paging (look up the page table). Naively, paging alone requires two additional memory reads per access -- one for the page directory entry, one for the page table entry.
Implementing natural neighbour interpolation implies the construction of a geometric Voronoi diagram, however this is not strictly the case. Since the Delaunay triangulation is the dual graph of the Voronoi diagram, all the information needed to perform natural neighbour interpolation is already implicit within the triangulation itself. Algorithms to determine natural neighbours from the Delaunay triangulation can be found in several papers within the literature[4][5]. Unfortunately the relative complexity of natural neighbour interpolation means that it is slower than barycentric interpolation by a considerable margin.

该ETF目前首次在其上升的50日简单移动平均线处获得支撑，自其突破109.02美元的双底枢轴位以来，这是一个往往相当理想的入场点。在此处建立仓位是合理的，并且有望在其突破新形成的双底触发位126.55美元上方时进行加仓；这一底部形态始于1月23日出现的一根十字星。
