Definition of DFS and BFS DFS的wikipedia定义: Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible ...

To solve the problem, this paper proposes the improved algorithm which combines the Branch and Bound method based on Depth-First-Search (DFS) and Breadth-First-Search (BFS). It helps construct the trajectory quickly on topological map. Experimental results validate the improved algorithm is ...
