dp 1 2 mst

Ideas: This is the first DP problem you've ever had when you started a DP game. In the game I thought of a state transition equation, f[i][j] [k][l][2], I and J are expressed in line I J, K and L represent the energy of man and sword, and the last one-dimensional 0 indicates that the current energy is replenished, 1 in

Obviously, the winning rate and negative rate of each round are fixed. Therefore, set PSC as the winning rate, pls as the negative rate, and peq as the flat rate, The winning rate and negative rate in each game can be determined, The odds and negatives in a stage

Must have a meeting point, the value of the meeting point can not be taken, ask two people can get the maximum path and how much?

Question] For a given 01 matrix, obtain its largest full 1 sub-matrix. [Idea] DP. [Hdu1506] Problem address: http://acm.hdu.edu.cn/showproblem.php? PID = 1, 1506 This question can be converted to the corresponding maximum value in the one-dimensional array. First, use two arrays L [] and R [] to record the greater range of the left and right sides of a vert

A dp example is used to provide a matrix. You need to find a path from top left to bottom right, so that the number at the end of the result multiplied by the number on this path is the least. First, consider that the number of the entire matrix is positive. Dp [I] [j] records two values, the minimum number of 2 at this point and the minimum number of 5. The fina
