架设广播线路时,如何使广播站到各接收点的连线最短?引水开渠时,如何使水源到各灌溉点的渠道最短?等等。诸如此类的问题,都是属于路线的确定问题。目的都是选择最短路线,以减少人力、物力及投资,节约运力等。因此,合理确定路线是农村的一个常见问题。下面介绍几种解决这类问题的方法。
When setting up a broadcasting line, how to make the connection between the broadcasting station and each reception point be shortest? How to make the water supply to the irrigation points with the shortest channel when leading the water? All these problems belong to the problem of determining the route.

Here are some ways to solve this type of problem.
