This is to give n vertices and each vertex has a probability, you need to divide the N points into W sets so that the minimum N1 value of the algorithm defined below is the sum of the number of points in the integration, the following is an example of dividing two sets. The coefficient above is the total number of the first wi sets. =N1 + (N1 +N2) = 3 (0.3 + 0.05 + 0.1) + (3 + 2) (0.3 + 0.25) = 3X0.45 + 5X0.55 = 4.1 We know that we won't let a high probability hit a big coefficient. So we so

In the best case, it is impossible to cross a light bulb. Why? Because it is cost-effective to replace a with C. If a with B, it is not cost-effective to replace a and B with C. Then there is simple DP. # Include Ultraviolet A 11400 lighting system design DP

Question: There are some stones, each of which has a value (1 ~ An integer in column 6). Now we divide the stone into two groups, Ask if they can be divided into two groups with the same value. Analysis: DP, 01 backpack. If the total size of a backpack is half, you can determine whether it can be fully filled. Note: If the data size is large, the binary shard Shard is used. # Include Ultraviolet A 711-dividing up
