A heuristic h(n) is consistent (monotone) if, for every node n and successor n', ____.
A heuristic h(n) is consistent (monotone) if, for every node n and successor n', ____.
a)
h(n) ≤ cost(n, n') + h(n')b)
h(n) ≥ cost(n, n') + h(n')c)
h(n) = 0 for all nodesd)
h(n) is always larger than the true costExplanation
Consistency is a triangle inequality; every consistent heuristic is also admissible.Related questions
