HDU_3488 It is worth mentioning that if we use the KM algorithm to find the perfect matching of minimum weights, we need to initialize the edge weight to the MAX-G [I] [j] and then find the perfect matching of the maximum right, and then convert the result back. If you initialize G [I] [j] to-G [I] [j] to find the perfect matching of the maximum permission, the program I write Will time out, at the moment, I have no idea whether this idea is a problem or my writing is a problem. #include#inclu

HDU_3718 First, we need to convert the characters in the string into the number of [0, k-1] with the same meaning, and then scan the array sequentially, we can get the maximum value of various matching between the two sets of numbers, this completes the graph creation. Then use the KM algorithm to find the optimal match. #include#include#define MAXD 30#define MAXN 10010#define INF 1000000000char a[MAXN][5], b[MAXN][5];int visa[MAXN], visb[MAXN], x[MAXN], y[MAXN];int G[MAXD][MAXD], yM[MAXD], N,

HDU_3395 We can split a fish into two points, which respectively represent attack and attack, and then set the Edge Weight of G [I] [j] = 1 to value [I].^ Value [j], and then use the KM algorithm to find the optimal matching of the Bipartite Graph. #include#include#define MAXD 110#define INF 1000000000int yM[MAXD], G[MAXD][MAXD], N, value[MAXD];int A[MAXD], B[MAXD];int visx[MAXD], visy[MAXD], slack;char b[MAXD];int init(){int i, j; scanf("%d", N);

tree, The Edge (I,J) may be added to the equal sub-graphIn order for the A[i]+b[j]>=w (I,J) to always be true, and at least one edge is added to the equal sub-graph, d=min{a[i]+b[j]-w (i,j)},i in the interlaced tree, J is not in the interlaced treetime complexity: need to find an O (n) time augmentation path. Each augmentation requires an O (n) sub-index change. Each time you change the top, enumerate the edges to find the D value, the complexity is O (N2), and the total complexity is O (N4). S

distance s. When 1 times slack is made on each side, the branches that start from S and have a maximum level of 1 are generated. That is, the shortest path to the vertices with a maximum of 1 edges associated with S is found, and the 2nd-pass relaxation of each edge creates a 2nd-level branch, which means that the shortest path of those vertices connected by 2 edges is found .... Because the shortest path contains up to |v|-1 edges only, you only nee

is a user interface and icon design tool. Why must I download it? "Our design team partners use Skala to test the work in real time on the phone," he said. "We want to make sure our design looks OK on the high quality screen," "light's UX director Jannie Lai explained. 」 SKETCH This is a very simple operation of the Ui/ux design application. Why must I download it? "wirefram also has a good helper in visual design. "skully's design deputy director Josh Bloom said.

, I do is a student project is just a big job, but in fact same, you design a product or product in a function, always to solve a problem. Even if it is a very small example, you have been a friend punctuate design, the design exists also have his reasons, how did you think you got your final solution? That's what I care about. Here's a chestnut. I very much like the designer of the firm Metalab was designed by the famous slack | Crunchbase, a firm

for relaxation until the queue is empty.The expected time complexity O (ke), where k is the average number of incoming teams for all vertices, can prove that K is generally less than or equal to 2.Implementation method:Set up a queue that initially has only a starting point in the queue, and then establish a table that records the shortest path from the starting point to all points (the initial value of the table is assigned a maximum value, and the point to his own path is assigned to 0).

not belong to an equal subgraph. The X end is in the staggered tree, and the Y end is not in the edge (I, j) of the staggered tree. The value of A [I] + B [j] is reduced. That is to say, it originally does not belong to an equal subgraph, And now it may have entered an equal subgraph, thus expanding the equal subgraph. The problem now is to evaluate the value of D. To ensure that A [I] + B [j]> = w [I, j] is always valid, and at least one edge enters an equal subgraph, d should be equal to mi

To ensure that a [I] + B [J]> = W (I, j) is always valid, and at least one edge is added to an equal subgraph, D = min {A [I] + B [J]-W (I, j)}, I is in the staggered tree, J is not in the staggered tree Time Complexity:You need to find the O (n) Increment path. You need to modify the O (n) Increment path at most. During each increment, the enumeration edge is used to evaluate the D value. The complexity is O (n2
