different graphs

1. Free Pen Tool The pen tool is a useful tool in PS, but not very well mastered. It's easy to draw a straight line with it, but it's more difficult to draw a curve. If you are proficient in the pen tool, you can use it to make precise selections, draw different shapes, create vector masks, and much more. If you want to make the path work easier, try using the free pen tool. It allows you to use anchor points for free painting without the need to use

, and each vertex has an edge between the other vertices, it is called a full graph without direction. Obviously, there are N (n-1)/2 edges in an absolute total graph with n vertices. Similarly, the number of edges in a directed full graph with n vertices is n (n-1), meaning that there are two edges with opposite directions between any of the two different vertices.④ degrees, degrees and degrees of penetration. The degree of Vertex v refers to the num

Use three ways to realize the storage of graphs to adapt to different situations.Reference: ACM-ICPC Programming Series--Graph theory and applicationMode 1: adjacency matrixAdjacency matrix is the simplest and most common one of the data structure of the graph.Implementation: The two-dimensional array map[maxn][maxn],map[i][j] represents the distance from point I to to J.Initialize: map[i][i] = 0,map[i][j]

is, the element of the array can be another array Conly the size of the array and the address of the first element is the compiler directly determinesOf4. Use Calloc to apply for dynamic spaceCalloc prototype: void *calloc (size_t num_elements, size_t element_size);parameter Description:Num_elements: The number of required elements Element_size: The number of bytes per elementDifference from malloc: calloc initializes it to 0 before returning a pointer to memory, and there is a

The difference between the algorithm and my above is that the timing of the output point is

multiple rows, and one column changes to multiple columns The above is a 4*4 square, with ### in the square representing the wall. We need to build a bunker where there is no wall in the table, in addition, to ensure that no two bunker blocks can attack each other, ask how many bunker blocks can be built at most? Is it like the first question? If we create a graph like the first question, the final maximum match is the matching of rows and columns. In addition, this match satisfies that all th

While good color schemes are now handy, it's still hard to find the right color scheme for data visualization. Because of the unique attributes of the information map, it is necessary to satisfy the rich and not messy color matching requirements while ensuring the clarity of color recognition. However, even if you are not sensitive to color, with today's dry goods mentioned in the 3 tips, you can easily create a good-looking information map. In the case of information

// ********************************* The following is a reprinted *** **************************************** Bipartite Graph Matching Algorithm Summary Hungarian algorithm for maximum matching of bipartite graphs A bipartite graph is such a graph. Its vertices can be classified into two sets X and Y. All edges are associated with two vertices. Exactly one belongs to set X, and the other belongs to set Y. Maximum matching: the matching with the large

variable diagram is described here, do not make the chart too complicated, otherwise you will lose the chart "intuitive" advantages.To show the correlation of 3 variables, it is best to use three-dimensional coordinates of the three-dimensional statistical chart, but because in fact still on the plane to the three-dimensional diagram, the three-dimensional map is not convenient to use.(1) When a variable is a categorical variable, the two-dimensional graph can be expanded, so that the two-dimen

For example, the red edge in Figure 3, Figure 4, is the match of Figure 2.We define matching points , matching edges , unmatched points , mismatched edges , and they are very obvious. Example 3, 1, 4, 5, 7 is the matching point, the other vertices are unmatched points, 1-5, 4-7 is the matching edge, the other edges are non-matching edges.Maximum match : A match with the largest number of matched edges in all matches of a graph, called the maximum match for this graph.

1. Problem description and understandingThe strategy followed by depth-first Search,dfs, as its name Depth, is to search as "deeper" in the diagram. In depth-first search, the newly discovered vertex v is explored if the vertex is not explored from its starting edge. When all the edges of V have been explored, search for "backtracking" to the vertex from which Vertex v is found. This process continues until all vertices that are from the source point are found. If there are no vertices found in
