It would be AI by the standards of A*, maze solvers, and similar. It isn't ML and doesn't isn't related to that branch of AI. Should graph search be considered AI? This gets us to the root of the issue, which is how do we consider something AI or not and to what extent has that definition changed as some problems have become trivial or commonplace. Machine learning is a bit easier since you can create much strong classifications around the need to teach, to feed it data with expected results, before it is useful to get a response (or otherwise give it a way to evaluate data it generates and then feeds itself). However there are a number of techniques that predate ML, or at least having fast enough computers to have worthwhile success at ML, and thus we are left with determining some way to objectively classify those as either AI or not.
