   The Manhattan Distance is the total of the absolute values of the discrepancies between the x and y coordinates of the current and the goal cells. The formula is summarized below - h = abs (curr_cell.x – goal.x) + abs (curr_cell.y – goal.y) We must use this heuristic method when we are only permitted to move in four directions - top, left, right, a...

   It is nothing more than the greatest absolute value of differences between the x and y coordinates of the current cell and the goal cell. This is summarized below in the following formula - dx = abs(curr_cell.x – goal.x) dy = abs(curr_cell.y – goal.y) h = D * (dx + dy) + (D2 - 2 * D) * min(dx, dy) where D is the length of every node (default = 1) a...

   The Euclidean Distance is the distance between the goal cell and the current cell using the distance formula: h = sqrt ( (curr_cell.x – goal.x)^2 + (curr_cell.y – goal.y)^2 ) We use this heuristic method when we are permitted to move in any direction of our choice.

   What is the a* algorithm based on?

   • The core of the A* algorithm is based on cost functions and heuristics. It uses two main parameters: g (n): The actual cost from the starting node to any node n. h (n): The heuristic estimated cost from node n to the goal. This is where A* integrates knowledge beyond the graph to guide the search.
