uch as Artificial Intelligence, where the answer is not necessarily “fixed”. The “answer” is judged more or less on a continuous scale. In these situations different algorithms are compared and the results are ranked. For example, a metric similar to a lab-rat maze test for intelligence testingcan be performed to evaluate performance.However, just because a given algorithm is known to be better, this does not tell us if it is the “right” or only possible algorithm. It might be the “best known” at a given point in time, but not much can be concluded beyond that. As expounded upon later,we don’t know what we don’t know.
