WebGreedy best-first search (GBFS) and A* search (A*) are popular algorithms for path-finding on large graphs. Both use so-called heuristic functions, which estimate how close a vertex is to the goal. While heuristic functions have been handcrafted using domain knowledge, recent studies demonstrate that learning heuristic functions from data is ... WebGreedy Best – First Search resembles depth – First Search in the way it prefers to follow a single path all the way to the goal, but will backup when it hits a dead end. It suffers from …

You might want to review how a best-first search works. It takes a step based on (for example) an heuristic, but can come back to reconsider that later if it doesn't find a solution. That's why it's a "best-first" not a "best-only" search. This means that backtracking can happen, which you need to take into your analysis. s o s women to the sea 2
When would best first search be worse than breadth first search?
WebGreedy best-first search is in most cases better than BFS- it depends on the heuristic function and the structure of the problem. If the heuristic function is not good enough it can mislead the algorithm to expand nodes that look promising, but are far from the goal. Here is one simple example WebGreedy best-first search Use the heuristic function to rank the nodes Search strategy Expand node with lowest h-value Greedily trying to find the least-cost solution – PowerPoint PPT presentation.
