The reverse of a single-chain table is always remembered. The reverse placement of a single-chain table can be implemented in multiple ways. This article is a summary of the reverse placement problem: First, use the three-pointer method. The three pointers are used to respectively record the precursor nodes of each node, its own nodes, and the post-drive nodes. The while loop is used to continuously adjust the order, and then move the operation point by point. The three pointers in China should

Network flow First, the number of each column in each row is calculated. The value of each row minus C, the value of each column minus R Then the edge is connected between each row and each column, with a capacity of 19. In this way, the (I,J) traffic is equivalent to (I,J) the value-1. This avoids the awkward situation where the flow is 0 and does not correspond to the answer. #include #include#includeusing namespacestd;Const intMAXN = ++Ten;Const intMAXM =100000+Ten;Const intINF =0x3f3f3f3f;in

disrupts the bad_boxes of the data. Since the TLD tracks only one target, we have determined the target frame, so that all other images except the target frame are negative samples, without affine transformations, as follows: Due to the previous overlap of less than 0.2, are classified into bad_boxes, so the number is quite many, the variance is greater than var*0.5f bad_boxes are added negative samples, as above, need Classifier.getfeatures (patch,grid[idx ].sidx, Fern), and Nx.push_back (Make

Maximum flow. A stream can correspond to a distribution method. It is clear that the maximum flow can represent the maximum number of matches #include #include#includeusing namespacestd;Const intMAXN = -+Ten;Const intMAXM =100000+Ten;Const intMAXL = -;Const intINF =0x3f3f3f3f;CharS[MAXN][MAXL],T[MAXL],T2[MAXL];intG[maxn],v[maxm],nex[maxm],f[maxm],eid;intId[maxn],vid;ints,t;intD[MAXN],GAP[MAXN];intn,m,k,a1,a2;voidAddedge (intAintBintF) {V[eid]=b; F[eid

less than the maximum length I have retained, then no more search, Skip directly.Another situation is that the number of BFS out of the length and the maximum number of previous reservations are equal? Now that the BFS has been used for pre-judgment, it is better to record the number of the longest distances that have arrived from that point. Then compare this number with the maximum number of reservations, and if it's small, then don't go one step further.#include"Iostream"#include"CString"#in

Network flow Presumably we all know, in this not too much to repeat. One of the problems in network flow is that you ask for the maximum flow, and for this problem, many computer-based computers give many different algorithms, here-as the title says-we only introduce one of them-\ (\tt{dinic}\)Dinic is a better algorithm in the maximum flow algorithm, its thought inherits the (ford-fulkerson\) algorithm, but has a great improvement to the FF algorithm. Dinic greatly improves the efficiency of th
