WebGreedy algorithm combined with improved A* algorithm. The improved A* algorithm is fused with the greedy algorithm so that the improved A* algorithm can be applied in multi-objective path planning. The start point is (1,1), and the final point is (47,47). The coordinates of the intermediate target nodes are (13,13), (21,24), (30,27) and (37,40). WebAlgorithm: Step 1: Place the starting node or root node into the queue. Step 2: If the queue is empty, then stop and return failure. Step 3: If the first element of the queue is our goal node, then stop and return success. Step 4: Else, remove the first element from the queue. Expand it and compute the estimated goal distance for each child.
