"WebUsually, when we write an algorithm, we are interested in knowing if the solution the algorithm provides is the correct one for the problem it solves. This can sometimes come in the form of a convergence. In general, algorithms have what we call metrics. A metric is a number that we give to a given result that the algorithm produces.
