S4E35: 永不重复三次的图厄-莫尔斯序列

from 大老李聊数学(全集)

图厄——莫尔斯序列,构造规则:从0开始,把0替换成01;把1替换成10。它的前几项是:0, 01, 0110, 01101001, 0110100110010110, 01101001100101101001011001101001....它是“无立方”字符串,永不出现“AAA”模式。ABBA制 2016年年,国际足联(FIFA)曾经宣布引入新的互射十二码机制,由传统的轮流互射五轮,改为“ABBA”制,意即抽中先射的一支球队射完第一轮后,后射的球队连射两球,然后先射的球队再射两球,如此类推。此举是由于多项研究已表明抽中先射的一方会有一定程度的优势,而数据亦指出先射的一方有不少于60%的胜率。因此,在2017年提出试验方案,在部分赛事试行全新的ABBA制互射十二码。但经过两年试验之后,已被证实不是特别受欢迎,主要是因为此方法过于复杂,而足球本身是一项简单和传统的比赛,所以国际足协已经在2019年决定不再使用此方法。喜马拉雅FM:https://www.ximalaya.com/keji/6310606/  (欢迎加入Ximi团)微信关注:dalaoli_shuxue B站: https://space.bilibili.com/423722633 知乎:https://zhuanlan.zhihu.com/dalaoli-shuxue/
