Random permutation

原声例句
万物简史

As these endlessly bumped and collided, they fractured or split or recombined in endless random permutations, but in every encounter there was a winner, and some of the winners grew big enough to dominate the orbit around which they traveled.

随着这些微行星无休止地碰撞,它们或破裂,或分解,或在无休止而又随意的置换中重新合并,但每次碰撞都有一个赢家,有的赢家越来越大,最后主宰了它们运行的轨道。

英语百科

Random permutation

A random permutation is a random ordering of a set of objects, that is, a permutation-valued random variable. The use of random permutations is often fundamental to fields that use randomized algorithms such as coding theory, cryptography, and simulation. A good example of a random permutation is the shuffling of a deck of cards: this is ideally a random permutation of the 52 cards.
