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. WebSome of these methods give you guarantees on convergence. A first step is to observe the shape of f ( x) for typical values of the free parameters, as a general study risks to be arduous. Note that you can absorb the two parameters M and r in A and B. Interestingly, you can rewrite the second relation as.
