It depends on what you mean by optimal. A* will always find the optimal solution (that is, the algorithm is admissible) as long as the heuristic is admissible. …
Apr 6, 2023 · If A* employs an admissible heuristic and h (goal)=0, then we can argue that A* is admissible. If the heuristic function is constantly tuned to be low with respect to the true cost, i.e. h (n) ≤ h* (n), then you are going to get an optimal solution of 100%.
In computer science, specifically in algorithms related to pathfinding, a heuristic function is said to be admissible if it never overestimates the cost of reaching the goal, i.e. the cost it estimates to reach the goal is not higher than the lowest possible cost from the current point in the path.
When using A* (or any other best path finding algorithm), we say that the heuristic used should be admissible, that is, it should never overestimate the actual solution path's length (or moves). How does an admissible heuristic ensure an optimal solution? I am preferably looking for an intuitive explanation.

Sep 3, 2016 · The definition of an admissible heuristic is one that "does not overestimate the path of a particular goal". I am attempting to write a Pac-Man heuristic for finding the fastest method to eat dots, some of which are randomly scattered across the grid. However it is failing my admissibility test. Here are the steps of my algorithm:
In computer science, specifically in algorithms related to pathfinding, a heuristic function is said to be admissible if it never overestimates the cost of reaching the goal, i.e. the cost it estimates to reach the goal is not higher than the lowest possible cost from the current point in the path.
