A* (pronounced "A-star") is a graph traversal and path search algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. One major practical drawback is its space complexity, as it stores all generated nodes in memory. Thus, in practical travel-routing systems, it is generally outperformed by algorithms which can pre-process the graph to attain better performance, as well as memory-bounded approaches; however, A* i…

May 30, 2022 · A) Exact Heuristics – We can find exact values of h, but that is generally very time consuming. Below are some of the methods to calculate the exact value of h. 1) Pre-compute the distance between each pair of cells before running the A* Search Algorithm.
