2013年1月13日,小来和小谷将筹划已久的一项地铁极客行动付诸实践:买一张两元钱的地铁通票,不出站,计划17个小时内通过北京所有的地铁站点(除机场线)。他们于当天清晨5点15分出发,晚上10点40分结束,历经319站次,560公里,用17个小时25分钟完成了这次挑战,比数学建模预计的时间仅仅多了25分钟。数学建模画出路线小来是中科院的在读博士生,专攻计算机软件。有一次,小来在微博上看到一道好玩的面试题,要求在尽可能短的时间内走一遍北京的地铁站,并且只在地铁内换乘,不出站。这个题目也引起
On January 13, 2013, Koizumi and Kobayashi put into practice a long-awaited Metro Geek: buy a two-dollar subway pass without leaving the station and plan to go through all of Beijing’s metro lines within 17 hours Site (except airport line). They set off at 5:15 the same day and ended at 10:40 pm, finishing 319 stops and 560 km in 17 hours and 25 minutes, just 25 minutes more than the mathematical modeling was expected. Mathematical modeling draw a small way to the Chinese Academy of Sciences doctoral students, specializing in computer software. Once, a small to see a fun interview on Weibo, asking to walk in the shortest possible time in Beijing’s subway station, and only within the subway transfer, do not leave the station.
