Test instructions: Give a grid size in which to find a base station, so that the square of the distance between each user (Euclidean distance squared), and to any of the communication distance (Manhattan distance) the total distance (cost) the smallest. In fact, to each user's distance to the minimum, to the communication company to be as close as possible, distance is the price.Idea: At first feel the need
With the rapid development of mobile communication, it becomes more and more important to solve the problem of indoor cover and capacity, and the micro-cell base station becomes an important means to improve the indoor coverage effect and to increase the special area capacity.
The importance of 3G indoor coverage
Good network coverage, especially indoor coverage is the key to the success of 3G, NTT DoCoMo
After several days of research and testing, we finally solved the positioning code for the base stations of China Unicom 2G, China Mobile 2G, and China Telecom 3G.

The old tracer tribe recently elected Dalong as the new chief of the tribe. As the saying goes, the first thing Dalong will do after taking office is to improve the communication among the villagers. The tracer tribe has a vast territory. People usually need to communicate with each other by using pigeons to transmit information. This method compromises the timeliness of information. Dalong, who graduated from "Information Whampoa", decided to build a communication system for the vil
