WebNov 25, 2024 · A* Algorithm (): Add start node to list For all the neighbouring nodes, find the least cost F node Switch to the closed list For 8 nodes adjacent to the current node If the node is not reachable, ignore it. Else If the node is not on the open list, move it to the open list and calculate f, g, h. WebThe algorithm is as follows- Step-01: Define a list OPEN. Initially, OPEN consists solely of a single node, the start node S. Step-02: If the list is empty, return failure and exit. Step-03: Remove node n with the smallest value of f (n) from OPEN and move it to list CLOSED. If node n is a goal state, return success and exit. Step-04:
