Test instructions: Chinese question.Idea: First, according to the sum of the horizontal ordinate and the odd conversion into a bipartite graph, for (I, j) and it only conflict (I-1, J) (I, j-1) (i + 1, j) (I, J + 1) 4 squares,Parity is reversed. If i + j is odd then and the surrounding 4 points are connected, then the problem is converted to a bit of power and-the minimum point weight coverage of the binary graph.

The study of the data structure of Min, in which the diagram in the chapter of graph theory, actually resembles a tree traversal, is applied to two very interesting structures: stacks and queues. In the process of deep traversal, it is necessary to record the path of the coming time, and in traversing to the last branch of the graph, we need to pass out the stack, get to the upper level of the node, in the process of breadth traversal, the current access when the node into the queue, when all th

match:(1) Minimum vertex coverage of a binary graph: with the fewest points, each edge is associated with at least one point.Maximum number of matches = minimum point coverage (Konig theorem)(2) The largest independent set of the binary graph: Select the most points in the graph, so that any selected two points are not connectedMaximum number of matches = maximum Independent number(3) Minimum path coverage: For a DAG (directed acyclic graph), select the minimum path so that each vertex belongs

The algorithm is as follows:Template Three: Shortest path (Dijkstra algorithm) The shortest path problem is a classical algorithm problem in graph theory research, which aims to find the shortest path between two nodes in graph (composed of nodes and paths). The Dijkstra algorithm uses a dist[] array to store the cost of reaching a point, corresponding to its subscript, and a path[] array to store the subscript of a vertex that passes before it reaches th
