Breadth-First traversal (Breadth-first traverse,bfts), called breadth-first search, is a traversal strategy for connected graphs. It is called the breadth-first traversal because his mind begins with a vertex V0, radiating the first to traverse the wider area around it.Algorithm description Given figure g= (v,e). V is a collection of nodes, and E is a collection of edges.Set an Access flag bit vflag (i) indicates the access of node I,

Before preparing to do Hiho, on-line search about the largest independent set of graphs;See a paper, said to be able to "the general graph of the minimum vertex cover set problem" of the hybrid greedy algorithm;I look like a very good ah, ran to study the majority of days of this paper, found that the actual is a very general approximation algorithm, in special cases, the deviation is great;After the implementation of the actual to do the problem, fou

Figure showsThe previous blog has already said two representations of the graph, one is the adjacency list, and the other is the adjacency matrix method.The front is suitable for sparse graphs, and the latter is naturally suitable for dense graphs.Graph creating adjacency matricesAdjacency matrix is actually a two-dimensional matrix, in front of the diagram is already simple to say, directly set up a direct int G[NumVertex][NumVertex] input on the goo

Depth-First traversalIn the traversal of graphs, depth-first traversal and breadth-first traversal are the most common and simplest of two traversal methods.The idea of a depth-first traversal is to look down, find the end, and then look for other branches.In the previous blog I have written breadth-first traversal (BFS).Portals to look at: breadth-first traversal of graphsCode implementationThe difference between the implementation and BFS here is th

POJ 1966 Cable TV NetworkLinks: http://poj.org/problem?id=1966Test Instructions: in a cable TV network, the repeater connection is bidirectional. If there is at least one route between any two repeaters in the network, the repeater network is called connected, or the repeater network is not connected. An empty network, and a network with only one repeater, are considered to be connected. The safety factor F of a network with n repeaters is defined as:(1) F is n, the remaining network is still co

Conclusion: The differences and connections between these graphs are very important.

1. The characteristics of adjacency matrix (non-direction graph): The adjacency matrix of graphs is stored by using two arrays to represent graphs: 1.) A one-dimensional array stores vertex information in a stored graph. 2.) A two-dimensional array (called an adjacency matrix) that stores information about an edge or arc in a graph. In the figure above we set two arrays: Vertex array: vertex[4] = {V0

The deep search algorithm is necessary for programmers, not only to be, but also to be skilled. In the ACM competition, Deep Search also holds a very important part. This paper uses explicit stack (non-recursive) to realize the depth-first traversal of graphs, hoping that we can learn from each other.The basic idea of the stack implementation is to kick a node with all the inaccessible "Neighbors" (that is, "a layer of neighbor nodes") into the stack,

......Sno_of_streets eno_of_streetsThe first line of all data set contains a positive integer no_of_intersections (greater than 0 and less or equal to 120), Which is the number of intersections in the town. The second line contains a positive integer no_of_streets, and which is the number of streets in the town. The next no_of_streets lines, one for each street in the town, is randomly ordered and represent the town ' s streets. The line corresponding to Street K (k There is no blank lines betwe

Step one, open the excel2007, and now we begin to draw a sine curve. To enter the data, the input method is to enter radians and sin on the a1/b1, then enter 1-360 directly below the A1, enter the formula "=sin (A2*PI ()/180)" on the B2. Now the mouse is placed in the lower right corner of the cell, and when the mouse turns into a small black cross, pull down and pull through 360 columns. As shown in the figure: Step two, now that the data input is complete, we begin to arrange the data,
