Link: HDU 5009 paint pearls Given the target color of a beaded sub, We Need To color these beads. Each time we can select the beads in a certain interval, the price is the square of the number of colors in this interval, the minimum cost is required. Solution: DP [I] indicates the optimal cost of I. After optimization, if the square of K (total color) is greater than N, the loop can be directly jumped out, when DP [I]> DP [I + 1], you can consider tra

From the past to the next DP; Discretization first; Assume that DP is at position I. Las [I] indicates the last position of the I-th color. T [k] indicates that the minimum subscript W (T [I], I) = K is satisfied, w (a, B) indicates that from a, A + 1, A + 2 ...... the number of different colors in the B interval. Then, update the T array each time, and then update the DP array. K only needs to enumerate from 1 to SQRT (N), so the complexity is (N * SQRT (n )). There are two situations when upda

Question: Every time you buy a pearl, you need to pay an extra ten yuan for it, but you can buy high-quality pearls to replace it (then you only need to pay the extra 10 Pearl money, but the price of each Pearl changes) This is a DP. To make DP [I] the minimum cost of buying only the first Pearl, The state transition equation is DP [I] = min (DP [I], DP [J] + sum ); Here, after j Sum is a good solution. Someone asks, this state transfer can only be u
