A* search orders nodes by the evaluation function ____.
A* search orders nodes by the evaluation function ____.
a)
f(n) = g(n)b)
f(n) = h(n)c)
f(n) = g(n) - h(n)d)
f(n) = g(n) + h(n)Explanation
g(n) is the cost so far and h(n) is the estimated cost to the goal; A* expands the node with the smallest sum.Related questions
