用于逐步删除随机项目的首选 Scala 集合? [英] Preferred Scala collection for progressively removing random items?

问题描述

我有一个需要多次迭代的算法，每次迭代都会对集合中的项目进行评分并删除得分最高的项目.

I have an algoritm which takes many iterations, each of which scores items in a collection and removes the one with the highest score.

我可以用初始填充填充 Vector，不断将其替换为 var，或者选择可变集合作为 val.哪个可变集合最符合要求?

I could populate a Vector with the initial population, continually replacing it as a var, or choose a mutable collection as a val. Which of the mutable collections would best fit the bill?

推荐答案

您可以考虑使用 DoubleLinkedList，它有一个方便的 remove() 方法来删​​除当前列表单元格.

You could consider a DoubleLinkedList, which has a convenient remove() method to remove the current list cell.
