Depth-first search with goal iterative Question: I have this piece of code here that is an iterative DFS algorithm, and right now it is giving an output of the nodes that it has visited. I want an output that only gives me a direct path to the goal node, how can I do that? P.S …
Is it possible to do a depth first search iteratively without copying visited nodes? Question: Background I am searching a 2D grid for a word. We can search left/right and up/down. For example, in this grid, searching for "abef" starting at (0,0) will return True Example (grid1): Where I’m at The recursive version gives expected …
deceptively simple implementation of topological sorting in python Question: Extracted from here we got a minimal iterative dfs routine, i call it minimal because you can hardly simplify the code further: def iterative_dfs(graph, start, path=[]): q = [start] while q: v = q.pop(0) if v not in path: path = path + [v] q = …
