Describe the a* search and give the proof of optimality of a*.

1.	Describe the a* search and give the proof of optimality of a*.
Answer» "A* search in the computer science is an algorithm that is widely used in the PROCESS of pathfinding and graph traversal that is the process in which a path is FOUND between the multiple POINTS that are known as nodes. There are two condition in which A* is optimal, • The monotonic heuristic condition, if h(ni)< h(ni+1), then the real-cost(ni)< real-cost(ni+1) • The admissible heuristic condition as it will never OVERESTIMATE the cost. "

"A* search in the computer science is an algorithm that is widely used in the PROCESS of pathfinding and graph traversal that is the process in which a path is FOUND between the multiple POINTS that are known as nodes. There are two condition in which A* is optimal,

• The monotonic heuristic condition, if h(ni)< h(ni+1), then the real-cost(ni)< real-cost(ni+1)

• The admissible heuristic condition as it will never OVERESTIMATE the cost.
