The A* Pathfinding Algorithm. (i) With regard to the A” path finding algorithm, define the following terms: node, open list. parent node, walkable, expanding a node (ii) Explain each of the three components of the A* cost calculation: F-G+ H. Explain also how each of these components is calculated, noting any assumptions made. [51 iii) In the 2D game depicted below, a ‘dragon’ character, under control of the computer, needs to navigate to a ‘knight’ character. Movements may only be made horizontally or vertically, by a full square at a time. The shaded squares represent impassable mountains. Write out in full the calculations associated with the first 5 squares expanded by the A* algorithm 51 (iv) Annotate and submit the diagram (detachable version on final page of this exam paper) with F, G, H values and parent node indication arrows for each square that will have been considered (i.e. added to the open list) before the correct path is discovered. 5 Show transcribed image text
