One, the cut point and the bridge of the non-direction graphFor g= (v,e)1. Cut point: xξv If you delete X and the edge with X, the graph is split into multiple unicom diagrams, then X is the cut point of the graph.2. Bridge (cut edge): eξe If you delete the E-map, the graph is split into multiple unicom diagrams, then E is the cut point of the graph.How to find t

, the number of times to restart the machine can be minimized.The task is to calculate the minimum number of times. Initially, both machines are running in mode No. 0.Ideas:Turn each task into a line, assuming that task I processes a a[x] point on a machine, on a B machine for b[y] points, connect a[x] and B[y],Cover all edges with the fewest points in a machine and B machine (all tasks are done in a minimal mode).This is the minimum point coverage problem, according to the K?nig theorem (the ma

This document lists: one, time module; second, dictionary and hash hash table; Third, the realization of the graph and the tree; Iv. member query; Insert ObjectOne, timing module (Timeit, CProfile)import timeittimeit.timeit(‘x = 1 + 2‘)Since learning the algorithm, it is important to calculate the time spent on the program, but it should be noted that: the Timeit () Timing function runs the relevant code snippet multiple times and averages it to impro

The so-called dichotomy chart: refers to the same part without edges, then this graph is a binary graph.Note: The following transfer from http://blog.csdn.net/dark_scope/article/details/8880547The Hungarian algorithm was proposed by the Hungarian mathematician Edmonds in 1965, hence the name. The Hungarian algorithm is based on the idea of sufficiency proof in Hall theorem, it is the most common algorithm of the part

First, the basic elements of the diagram1. Vertex/node (vertex);2. Edge (Edge), connecting two points, can be without direction can also be for the edge, you can for the right side can also be the right side;3. Connected graph: Any two points on the diagram are connected. That is, any two points are connected by one or more edges.4. Connected components: Maximum connected subgraph. That is ① is the subgraph of the

This paper illustrates the adjacency table storage and breadth first traversal method of C + + implementation graph. Share to everyone for your reference. Specifically as follows: Example: Creating a non-direction diagram as shown in the figure It is known from the above figure that the figure has 5 vertices, a,b,c,d,e respectively, with 6 edges. Sample input (enter in this format): 56Abcde0 10 20 32 32 41 4 Enter end (this row does not have to

The question is true God. Keep the dictionary to a minimum and, of course, try to get into the S1 when it has to go into S2. A[i] and a[j] cannot be pressed into the same stack ⇔ there is a k that makes i because a number can only go in and out one time, K should be in front so pop K when I and J are in the stack, If the two pop up on the same stack, the order is wrong. So we put this certain different stack of i,j to a side, we get a graph, and t

Graphic Introduction to depth first search 1. Depth First Search Introduction The depth-first search of the graph (Depth first) is similar to the tree's ordinal traversal. Its idea: Assuming that the initial state is that all vertices in the diagram are not accessed, from a vertex V, the vertex is first accessed, and then the depth-first search traversal graph is started from each of its inaccessible adj
