programming complexity advantage when some "extended version" Trees require LCA. For example, in a cactus diagram (a cactus diagram, each vertex in the diagram belongs to a simple ring at most), or in the yt Shortest Path, each edge belongs to a simple ring at most, if you change the father of a vertex in the expanded block to it, the graph becomes a tree. In fact, it is easier to find out the father's representation of the last tree. If we need to r

Paper notes: Dynamic Label propagation for semi-supervised multi-class Multi-label Classification ICCV 2013

natural transition matrix for vertex v can be defined as a normalized weight matrix:  So Σj∈v P (i, j) = 1. The note:p becomes symmetrical after normalization.The dataset table is X = {xl U Xu}, and XL indicates that the label data Xu represents untagged data. In the process of label delivery, it is very important that:clamping, that is, after each iteration, the label data label will be reset, this is to exclude interference, because these tagged data do not need to propagation, so as long as

Knight Travels/knight tour-visual Basic Solution

The question of Knight travel is seen in the seventh chapter of the visual Baisc 6 how to program Chinese version. On the 8x8 chess board, the Knight (walk: Two squares in one direction, one in the other) does not repeat the path of all the blanks on the board. The idea is to choose the corner of a grid as the starting point, all the road can go all the way to try again. To try 8^63 times, the calculation time is too long. It's better to make the chessboard into 5x5. In addition, the book sugges
