To delete some edges so that the start point and the end point are not connected, the number of edges to be deleted should be as few as possible when the sum of the right values of the deleted edges is the smallest. Obtain a ratio: the

first contain the number of the vertex and so ' + ' or '-' character, separated by one space. Character ' + ' means that Bob removes all arcs incoming to the specified vertex and '-' That's Bob removes all arcs Outgoin G from the specified vertex.Sample Input3 61 2 34 2 11 21 13 21 23 12 3Sample Output531 +2-2 +Test Instructions: give you a map, for point I delete all the edges into the point to pay the cost w[i]+ (case 1), delete all the edge from this point to pay the cost w[i]-, ask to delet

The algorithm is based on a theorem: for any S, T v∈, global minimum cut or equal to the original s-t minimum cut, or equal to the original image contract (s, T) the global minimum cut of the graph obtained from the operation. Algorithm framework: 1. Set the currently found minimum cut mincut to +∞ 2. Find out any s-t

Topic: Given an n-point, M-edge of the non-weighted graph, the weight of the edge is a positive integer. To make it a non-connected graph, what is the minimum total weight value to remove? N≤500, there is no self-ring in the figure, but there may be heavy edges (here test instructions not explained clearly). Stoer-wagner algorithm bare topic. English Wiki: Https://en.wikipedia.org/wiki/Stoer%E2%80%93Wagner_algorithmOne of the ideas of this algorithm is: for a undirected connected graph,

Hdu 3657 least cut active/odd/Even square fetch classic questions/least cut, hdu3657 Question: Take the number of squares. If the number is adjacent, pay a certain price. (Cost: 2 * (X Y) (start to use the fee stream, knock the upgrade version 3820, kneel down ...) Graph creation: for adjacent problems, the classic method is to create a bipartite graph for parity. For the adjacent two-point edge 2 * (X Y)

points inside a " b Create a new a to b m b pay the most price, They will definitely choose the optimal building plan. Ask you: City B needs to pay the greatest price. Analysis: The minimum cut will certainly divide the original image into two point sets. One is the set of S that can be reached by the source point , and one is the T -set that can reach the meeting point (reachable is for the residual network). Point a belongs to the S

The grabcut algorithm in OPENCV is implemented according to the article "Grabcut"-Interactive Foreground Extraction using iterated Graph Cuts. The algorithm takes advantage of the texture (color) information and the boundary (contrast) information in the ima

The main idea: to give a three-dimensional lattice, not a point is likely to be cut, the price is the weight of this point. The height difference of the adjacent cutting points cannot exceed D, and the minimum cost makes the top and bottom separate.Idea: Very bare minimum cut model, very God-built map.S-> the first floor, F:inf.All points--the dots below it, f:infA point of entry-and-out of a point, f:val[i

Restriction: The absolute value of the difference of the number of adjacent two squares must not exceed D.For a legal minimum total cost.This problem is a minimal cut model, just say the map.Map: Each point (x, y) is split into R points, (x, Y, z) to fill in Z (x, y).Then from S to (*, *

Topic Input Format The first line is a three positive integer p,q,r, representing the cut cake's long p, wide Q, and high R. The second row has a nonnegative integer d, which indicates smoothness requirements. Next is the matrix of R P row Q columns, the x row of the z matrix is V (x,y,z) (1≤x≤p, 1≤y≤q, 1≤z≤r).100% of the data satisfies the p,q,r≤40,0≤d≤r, and all the disharmony values given are not more than 1000. output Format Contains only an inte

Core idea: limits are expressed in Benlay with infinite capacity in the smallest cut. This is equivalent to a p∗q p*q matrix, with each matrix adding a [0,r] [0,r] number, and the difference between adjacent numbers does not exceed D D, while minimizing V (i,j,k) v (i,j,k). The first string the values of a lattice, that is (i,j,k) (i,j,k) (i,j,k+1) (i,j,k+1) with a capacity of V (i,j,k+1) v (i,j,k+1) of the edge; in particular, S S to (i,j,1) (i,j,
