WebJan 13, 2024 · For best-first search, you don't need a priority queue. You just need to track which nodes you have visited, and which node you are currently at. While your current node is not the target node, find the shortest edge that leads to an unvisited node, and set your current node to the node at the other end of that edge. Share Improve this answer WebHere is the part of the code that runs the algorithm, constructs the search path (if there is one), and shows in a step-by-step manner how it proceeds through the graph: result = …

WebThe best-first search algorithm starts the graph traversal by marking the start vertex as visited, i.e. putting it in the dictionary and placing it into the priority queue of candidate vertices.
