(plan of operation, including, map the basic storage methods, the operation of the map algorithm and C language programming. map of the search path traversal methods to the adjacency matrix and adjacency list of storage connected graph. Then, using the priority traversal algorithm depth of the matrix adjacent to the storage map and the adjacent forms storage plans. Depth-first traversal of the recursive algorithm (1) depth-first traversal algorithm (2) adjoining table depth-first search algorithm ( 3) adjacency matrix of depth-first search algorithm.)
