Although he always tries to does his homework completely and he can ' t solve this problem. As you know, he's really weak at graph theory; So try-to-help him in solving the problem. You is given a weighted directed graph with n vertices and m edges. You need to find a path (perhaps

as the last element of a continuous string. Then a [I] is the maximum value of the string and the number that can be extended forward is found, save it in L [I], and the same is true to the right. After preprocessing, consider the I position. If a [+ 1]-A [I-1]> 1, you can modify the I position (of course, you can also do not modify, modify or not modify to see

Question: Click to open the link Ideas: This is the first DP question to be encountered after the DP training. A state transition equation was created during the competition. f [I] [J] [k] [l] [2], and I and j represent column J in row I, K and L indicate the energy of man and sword. The last one 0 indicates that the current energy is added to man, and

I feel like I have to say a lot or don't say =. At that time, I was crying. Idea: we can regard the automatic machine as a directed graph, the state as a vertex, the letter as an edge, and then transfer it according to the value given by the # matrix. First, we need to pre-process the g

It should be said, which the circuit in Vologda are going to being rather simple. It'll be a rectangleN*MCells in size with a single circuit segment built through each cell. Each segment should is parallel to one of rectangle's sides, so only right-angled bends is on the circuit. At the picture below and samples is given forN=M= 4 (gray squares mean gopher holes, and t

E. pashmak and Graph Pashmak's homework is a problem about graphs. although he always tries to do his homework completely, he can't solve this problem. as you know, he's really weak at graph theory; so try to help him in solving the problem. You are given a weighted directed graphNVertices andMEdges. you need to find a path (perhaps, non-simple) with maximum number of edges, such that the weights of the edges increase along the path. in other words, each edge of the path must have strictly great

Original question: HDU 3362 http://acm.hdu.edu.cn/showproblem.php? PID = 1, 3362 I started to get greedy and found that it was too difficult and I had never done it. Later, I learned that the DP should be squashed. Question: the two-dimensional coordinates of n (n Since N is very small and there is no limit on the order of fixed points, we need to use State compression

Every time you guess wrong, I'll tell you whether the number is higher or lower. You call a pre-defined APIguess(int num)Which returns 3 possible results (-1,1, Or0): -1
