Test instructions: N number, divided into M-segment, to find the maximum of the M segment and, between the segments can not cross.Analysis:The difference between this problem and the maximal subsequence is that the requirements are divided into M-segments, so the approach is different. The actual practice is somewhat like a packet DP (the number of n is divided into M-groups), but the topic and the last written two group

Description a regular game before the start of the ticket work is underway. Each ticket is 50 yuan, the existing K (1 21 21 1Sample Output01HINT The main idea: DP is to see the relationship between the two states do not look at the whole, so dp[i][j] = Dp[i-1][j] is certainly satisfied, if the number of n is greater than or equal to M, the current can find the op

to be a, match string B, Dp[i][j] on behalf of B[1..I] and A[1..J] match successfully. Apparently dp[0][0] = true, for other situations: If b[i] = = '. ', then a[j] can be any character, Dp[i][j] transferred from Dp[i-1][j-1. If a[j] = = B[i], the same dp[i][j] is transferr

, which represents the balance on the card. mN=0 indicates the end of the data.Output for each set of inputs, outputs a line that contains an integer that represents the smallest possible balance on the card.Sample Input 1 50 5 10 1 2 3 2 1 1 2 3 2 1 50 0 Sample Output -45 32 In fact, the two-dimensional DP equation should be Dp[i][j]=max (Dp[i-1][j],

Some DP and DP miscellaneous questions 1. [HNOI2001] Product Processing A simple backpack, but I still wrote QAQ for a long time. The time range is smaller than 5. Obviously, one-dimensional backpacks are considered. dp [I] indicates that currently A consumes the minimum B consumption of I. Note: If (B [I]) dp [j] =

The question is that at least one string can be divided into several paragraphs, so that each paragraph is a palindrome string.At first, the direct interval dp,dp[i][j] represents the answer of the substring [i,j], but the length of the string 1000,100w state, a state is transferred from multiple states, and when it is transferred, it is enumerated so that time complexity is not feasible.And then I thought

Poj2342 -- hdu1520 -- Anniversary party (tree DP Exercise 1), tree dp Anniversary party Time Limit:1000 MS Memory Limit:32768KB 64bit IO Format:% I64d % I64uSubmit Status DescriptionThere is going to be a party to celebrate the 80-th Anniversary of the Ural State University. the University has a hierarchical structure of employees. it means that the supervisor relation forms a tree rooted at the rector V.

Question 2: Return Character Sequence (interval DP), return dpTime Limit: 256 ms single point time limit: Ms memory limit: MB Description Returns the number of subsequences of input strings. The reversed Character Sequence is still the same as the original sequence. For example, in the string aba, the input sub-sequence is "a", "a", "aa", "B", and "aba". There are 5 sub-sequences in total. Subsequences with the same content and different location

Dynamic Planning Learning Series-divide DP (2) and Plan dp The second question of Partitioned DP, wikioi 1039, is different from the biggest idea of the product of the first question. Question requirements: Divide a number into several parts and ask the total number of methods.Truth-solving ideas:In fact, it is a bit like some of the questions of Primary School

The concept of balanced number is given first: number n is the pivot of a certain digit in number n, the weighted value of each bit is (Digital xi * (posi-FULCRUM posi )), if there is a fulcrum in number n that makes the sum of all the weights 0, then she is the number of balances. For example, 4139, with 3 as the pivot, 4 * (4-2) + 1 * (3-2) = 9, 9 * (1-2) on the Right) =-9. The value on the left and right are 0. Therefore, 4139 is the number of balances. Now we provide an interval [l, r]. How

Before: In fact, my DP is so weak to learn the slope optimization is not good because my DP a little bit difficult to push out the state transfer equation >0However, I did not hesitate to learn the slope optimization (in fact, you just do the problem when used to the way to see a bit of the soul light!)No, we cut the text.—————————-line Cut is me >ωWhen we do DP

Practice: in fact, there is a root tree in the question. At first, I thought there may be multiple connected components. The data volume is so big, and I read the blog of the great god, and slowly hurt me... If the current node is a leaf node, Then DP [x] = 1-E [x]-K [x] + k [x] * DP [1] + sigma (P [I] * DP [fahter [I] ); If not
