The meaning of the question is as above, and contains a duplicate edge (if the duplicate edge is used, the two points can constitute an edge dual connection ). First, reduce the point to a tree, and find the diameter of the number. The farthest link, the remaining side (BRIDGE) is naturally the least. Here we have learned the method of tree diameter: The first time we select any starting point U for BFs, to reach the farthest point V (Level deepest), this point must be an endpoint of the tree's

Find the shortest path between two vertices The rule always sends an agent to the next city. The agent's work is to record the minimum fee information from the source point to other cities.Calculate the cost and construct an array to keep the shortest distance from the source point to other vertices. This distance varies during Algorithm Execution. Until the end, it stores the true shortest distance from the source point. Package COM. mapbar. structure;/*** class graph_shortstra.java * descr

ZOJ1015Test instructions Brief Description: Given an image without a direction, determine if there is a loop with a length greater than 3, and there is no chord on it (the edge of the connection ring on the different two points and not on the ring).The proposition is equivalent to the existence of a perfect elimination sequence for the graph.The so-called perfect elimination sequence: in the vi,vi+1,... vn VI and after the adjacent points with the vi form a regiment (complete sub-map).The MCS al

, LCA (t,3,9) = 3. Set the linear sequence A to the sequence traversal of the root tree T, i.e. a = [4,2,5,1,8,6,9,3,7]. By the nature of the middle-order traversal, we can know that the nearest common ancestor of any two-point u, V is always in the interval with the endpoint at the location of the two point, and the number is the smallest. give me a chestnut: Assuming that u = 8, V = 7, the interval defined by the two points is [8,6,9,3,7], and the interval minimum is 3, that is, node 3 is the

can only contribute one working day, that is, the outbound (to the sink point) capacity can only be 1, the size of the inbound edge is also 1, as long as a movie can work on that day, it is possible to select this day, that is, a line is established between the point corresponding to the movie and the point corresponding to the work day. Finally, a super source point is added, the capacity between it and the point of each movie is the work day required for the film (not infinite) **************

If U is the root node, it cannot be regarded as the cut point, but it depends on whether there are two or more V that can be searched out. Strongly Connected contraction point: you need to create more instk arrays to indicate whether a point is in the current search path (if a searched point is found in an u

Label:3 NEO4J Storage StructureNEO4J, there are 4 types of nodes, attributes, relationships and other files are used as the core storage structure, and each data item of the type of node, attribute, relation, etc. is assigned a unique ID, which is the index of the array when it is stored. This enables quick positioning with its ID as the subscript when accessed. Therefore, in the graph traversal and other o
