WebConsider making a breadth-first search into an iterative deepening search. We can do this by having aside a DFS which will search up to a limit. It first does searching to a pre-defined limit depth to depth and then generates a route length1. This is done by creating routes of length 1 in the DFS way. WebFeb 20, 2024 · When a dead-end occurs in any iteration, the Depth First Search (DFS) method traverses a network in a deathward motion and uses a stack data structure to remember to acquire the next vertex to start a search. Following the definition of the dfs algorithm, you will look at an example of a depth-first search method for a better …
