time complexity：时间复杂度

理论上,循序(sequential)演算法排序的时间复杂度(time complexity)为:Ω(n log n),如merge sort的time complexity为O(n log n). 也就是说,已经没有办法从演算法上著手来使这个问题获得实质上的改善了. 但是藉由平行化,我们可以取得相当显著的改善.

decorate：飾

更奇怪的是,尽管求合集和交集的操作在理论上是对称的,但是实际结果却与次序相关:对于cmp效率低下的问题,有效的解决方案是使用 Schwartzian 排序:修饰(decorate)各对象,进行排序,然后去掉修饰.

flow shop：流水车间

perfect：完美的

1956年Smith研究在没有工件误工的、所谓"完美的"(perfect)排序中寻找使平均完工时间为最小的排序问题,开创了研究多目标排序的先河. 然而,在实际问题中往往是允许工件误工的,也就是说,工件可以在交货期之后完工,即允许工件有延迟或者延误,
