Due to the convenience of wireless Internet access, enterprises are increasingly inclined to adopt wireless network technology when deploying networks. However, infinite network technology has a signal limitation. That is to say, a wireless router can only provide network connections for clients with signal coverage. Therefore, when deploying a wireless

expected value, the area with large probability should be placed in front of the access as far as possible.So first sort all probabilities from big to small. Then group, you can take a continuous paragraph into a group.F[I][J]: The first I, the minimum expected value into the J groupF[I][J] = min{F[k-1][j] + i*sum[k~i], 1#include #include #include using namespace Std;intMain () {intT scanf"%d", t); while(t--) {intN, W;Double sum[ the] = {0}, dp[ the][ the] = {0}, Total =0; scanf"%d%d", n, w); f

This technology is mainly used in the special mobile data communica

　　iphone uses cellular mobile network for slow resolution Step 1, when using 2G or 3G network, if the current network signal is not good, will certainly affect the speed of the Internet. Check the upper left corner of the iphone display for strong or weak signals. If the signal is poor, try changing the position. S

You is given n points on the straight line-the positions (x-coordinates) of the cities and m points on the same line-the positions ( x-coordinates) of the cellular towers.

The main idea: give a series of numbers, divide them into m parts, if the sum of the part I is AI, the 1th part to the section I total has the number of BI, then SUM=A1*B1+A1*B2+...+AM*BM, to find the smallest sum.First sort, big in front, and then grouped in such order, each group must be consecutive numbers, which can be easily proved by the neighboring Exchange method.The number of I is divided into J by D[i][j], and the sum of the number of first I is represented by the sum[i], and the enume

Analysis:A state is a set of ordered collections that do not intersect and are set to all regions. It is obvious that enumerating the elements of a collection is not bearable,Write the desired formula, you will find a greedy, when the size of each set is determined, the probability of a large priority access is optimal. It's easy to prove and intuitive.So first you sort from big to small. The definition state F[i][j] represents the minimum expectation of the group I, starting with J.Transfer is
