Week 05 of the Turing Award Series - how to tell if a bad answer is the algorithm's fault or the input problem's?
Forward errors are hard to compute in general because you need the right answer and then do the subtraction, but backward errors are much easier to compute. It’s how much you have to nudge the inputs to make your answer exactly right.
