近日这一幕温暖全网：1月24日，在四川泸州过江大桥上，一名年轻母亲将婴儿放下，转身攀上桥栏欲轻生。外卖小哥骑电瓶车擦肩而过，在后视镜中警觉不对，扔下车百米冲刺将人救下。警方赶到和市民对轻生者进行劝说时，小哥静静离开，继续送货。泸州市委宣传部证实，全网点赞的快递小哥已经找到，他叫罗虫董，今年20岁，是泸州市叙永县水尾镇人。
“奔跑的那一刻，我看见了他背后褴褛的披风，无形的英雄。四川的骄傲！！！”“名字里有个‘虫’，现实中的一条‘龙’。”“没有丝毫犹豫的拼命奔跑！勇敢温暖的年轻人，从事什么职业都会发光。”……评论区的网友留言同样温暖。
身为快递小哥，当他从后视镜中看到女子怪异的举动时，立即抢下了这个救命的“单子”，新年快递，安全送达！救命的“算法”是怎么计算的？
最值得夸赞的算法是响应速度，余光一扫，视觉从眼睛传递到大脑激发反应大约180毫秒，小哥没有一丝犹豫，就地折返拔起，以极限速度狂奔数十米，一个虎扑，雷霆之势让轻生者来不及反应就被抱离危险区。这一条算法，自动开启了生命至上的“抢单模式”，堪称“最美算法”。
据罗虫董事后说，当时他什么都来不及想，只想把她拉上来。我们相信，正是善良、勇敢、自信、果决这些“模块”在罗虫董身上早早储存绑定，他的大脑才会直接调用这些模块，做出效率最高的决策。也正是“原厂”绑定中摒弃了犹豫、猜忌、动摇等负面模块，才能让执行变得干脆纯粹，没有一丝拖泥带水。
还有一种算法是温度。接单最忌凉，汤凉了还能热，人心可不能凉。为什么我们常常痛恨明哲保身、袖手旁观的看客，就因为他们冷漠，他们凉薄，他们没有活力，奄奄一息。雪中尤须送炭，逆境更当鼓歌，想人之所想，急人之所急，这一份古道热肠，需要整个社会来温养弘扬，激励表彰。据悉，其从业的平台美团已授予他“先锋旗手”荣誉称号，并奖励一万元。我们点赞这样的正向反馈！
The "algorithm" of the food delivery industry can't be seen or touched, and it invisibly regulates the pace and enthusiasm of every delivery boy. On the road of life, we also need to temper modules and "algorithms" to schedule our pursuit of truth, goodness and beauty. The enthusiasm of the people, and the knowledge and action of righteousness and courage.
If the well-thought-out benefit calculation is called human calculation, and the rules that operate according to the rules are called heaven calculation, it is often "human calculation is not as good as heaven calculation".
At the moment when Luo Zongdong saved people, he probably didn't have time to "calculate" his own gains and losses. He didn't have time to "calculate" what would happen if the battery car was thrown and broke (later after the resumption, at least the rearview mirror was broken), it was delayed. What to do with the delivery... We praise this kind of coming forward. Luo Zongdong is not Luo's "impulsive". The rules he follows are the compassion that everyone has. Innocent feelings that are not stained with dust.
These "original modules" and "the most beautiful algorithms" are deeply rooted in our values. At critical moments, call them directly!
