Greedy search algorithm example
WebMar 8, 2024 · What A* Search Algorithm does is that at each step it picks the node according to a value-‘ f ’ which is a parameter equal to the sum of two other parameters – ‘ g ’ and ‘ h ’. At each step it picks the node/cell having the lowest ‘ f ’, and process that node/cell. We define ‘ g ’ and ‘ h ’ as simply as possible below.

WebThe A* search algorithm is an example of a best-first search algorithm, as is B*. Best-first algorithms are often used for path finding in combinatorial search . Neither A* nor B* is a greedy best-first search, as they incorporate the distance from the start in addition to estimated distances to the goal.
