"WebApr 4, 2024 · Greedy Best-First Search is an AI search algorithm that attempts to find the most promising path from a given starting point to a goal. The algorithm works by evaluating the cost of each possible path and then expanding the path with the lowest cost. This process is repeated until the goal is reached. " - Greedy bfs in python
