Poj 1915-knight moves (unidirectional BFS & bidirectional BFS comparison)

Link: knight moves It is not difficult to study two-way BFs. Like common BFs, two-way BFS only searches at the same time from the start and end points, reducing the search time. When the two search routes meet, the process ends. It seems that one year of Baidu's recruitment test is two-way BFS .... Next, compare the

Use BFS to solve the Maze problem and BFS to solve the Maze problemIn an n * n matrix, the path starts from the origin point (0, 0) to the end point (n-1, n-1). The path can only go in the upper, lower, and left directions, but only in the given matrix, calculate the minimum number of steps. N * n is the 01 matrix. 0 indicates that the grid has no obstacle. 1 indicates that there is an obstacle. Int mazeArr

Test instructions: Two-dimensional matrix, the guards from the outside to the inside to put two prisoners, asked the middle of the door to open the minimum number of times.Analysis:This question from the outside, so long as the matrix edge can go to the point (except the point of the wall) can be used as a starting point, there are two end points, so the direct lifting point of the search is not feasible. The practice is to use three times BFS, respec

How to achieve breadth-first traversal (BFS) and breadth-bfs

How to achieve breadth-first traversal (BFS) and breadth-bfs BFS process: 1. Access vertex V and Mark V as accessed Ii. vertex V entry queue 3. If the queue is not empty, execute the command; otherwise, the algorithm ends. 4. Obtain the right vertex u in the output queue. If the vertex is not accessed, access the vertex and mark it as accessed. 5. Find the first
