About:Partial sorting

An Entity of Type:Rule105846932,from Named Graph:http://dbpedia.org,within Data Space:dbpedia.org

In computer science, partial sorting is a relaxed variant of the sorting problem. Total sorting is the problem of returning a list of items such that its elements all appear in order, while partial sorting is returning a list of the k smallest (or k largest) elements in order. The other elements (above the k smallest ones) may also be sorted, as in an in-place partial sort, or may be discarded, which is common in streaming partial sorts. A common practical example of partial sorting is computing the "Top 100" of some list.

  • In computer science, partial sorting is a relaxed variant of the sorting problem. Total sorting is the problem of returning a list of items such that its elements all appear in order, while partial sorting is returning a list of the k smallest (or k largest) elements in order. The other elements (above the k smallest ones) may also be sorted, as in an in-place partial sort, or may be discarded, which is common in streaming partial sorts. A common practical example of partial sorting is computing the "Top 100" of some list. In terms of indices, in a partially sorted list, for every index i from 1 to k, the i-th element is in the same place as it would be in the fully sorted list: element i of the partially sorted list contains order statistic i of the input list.

  • 在计算机科学里,偏排序是排序算法的一个放宽的变种。全排序返回的列表中,每个元素都按一定顺序出现,而偏排序返回的列表中,仅有 k 个最小(或 k 个最大)的元素是有序的。其他元素(第 k 个最小之外) 也可能被就地排序后存储,也可能被舍弃。这常见于流式偏排序中。偏排序最普遍的实例是计算某个列表的 "Top 100"。 就索引而言,偏排序后的列表中,对每一个从 1 到 k 的索引 i ,都有第 i 个元素与全排列后列表保持相同位置:偏排序后列表的第 i 个元素包含了输入列表中的第 i 个顺序统计量。 (zh)
