1.听写包 答案：

Well, businesses have been able to use this approach of following simple rules when designingcomplex systems.For instance,

in telephone networks, when a call is placed from one city to another it has to connect through anumber of nodes along the way.
At each point, a decision has to be made: which direction does the call go from here?
Well, a computer program was developed to answer this question based on rules that are similarto the ones that ants use to find food.
Remember, individual ants deposit pheromones and they follow the path that is mostreinforced.
Now, in the phone network, a computer monitors the connection speed of each path andidentifies the paths that are currently the fastest,
the least crowded parts of the network.
And this information, converted into a numeric code, is deposited at the network nodes.
企业在设计复杂的系统时，可以使用这种遵从简单规则的方法。比如，
在电话网中，从一座城市打电话到另一座城市时，它在这个过程中要通过很多节点进行连接。
在每个节点，他们必须决定这通电话从这里要拨往哪个方向。
他们按照和蚂蚁用来找到食物的相似规则，设计出了一个电脑程序来回答这个问题。
别忘了，单个蚂蚁会留下费洛蒙，并且会沿着费洛蒙最强劲的那条路走。
在电话网络中，电脑会监控每条路径的连接速度，并辨认出这个网络中目前速度最快，
最不拥挤的部分。
而这个转化成了数字代码的信息被留在了网络节点上。
