Abstract
We analyze the computational complexity of the search algorithm called "Iterative-Deepening-A*" used in artificial intelligence, under some modest hypotheses. Our theoretical predictions, which are asymptotic, are shown to match the empirically observed behavior of the algorithm, even in relatively small searches.
