Question: Some circles on the plane must be used to connect the circles on the three points of 1, 2, and 3 with the least circle. Ideas: If the two circles can be connected, they are connected by edges and then the problem is transformed into a graph theory model. Then we only need to find the shortest path from 1, 2, 3 to the other points and then enumerate the intermediate points respectively. the distance to these three points is equal Why is it right to find the intermediate point ??
