Breadth first search branching factor

WebConsider the 8-puzzle problem. a. (3 pts) What is the maximum branching factor for this problem. b. (10 pts) Assume that for this problem goal state occurs at the depth 5. If depth-first search algorithm is used to solve this problem, what would be the maximum number (worst-case) of nodes that breadth-first algorithm takes to find the goal ... WebThe branching factor - the average number of children of the nodes in the space. ... This algorithm combines advantages of breadth first search with advantages of best first search. In the A* algorithm the score assigned to a node is a combination of the cost of the path so far A(S) and the estimated cost E(S) to solution. ...
