In this case the method consists simply to drawn in the plane the domain D and the contour plots and by inspection to find the points of contact at wich kmax and kmin ... In mathematical analysis, the maximum (PL: maxima or maximums) and minimum (PL: minima or minimums) of a function, known generically as extremum (PL: extrema), are the largest and smallest value taken by the function, either within a given range (the local or relative extrema), or on the entire domain (the … Meer weergeven A real-valued function f defined on a domain X has a global (or absolute) maximum point at x , if f(x ) ≥ f(x) for all x in X. Similarly, the function has a global (or absolute) minimum point at x , if f(x ) ≤ f(x) for all x in X. … Meer weergeven Finding global maxima and minima is the goal of mathematical optimization.

Webminimum values of a function are called extreme values or extrema. Accordingly in the third case, OC becomes the global maxima and X1C1 the global minima if we restrict in the interval of x to0 ≤x ≤x1. Let us consider the fourth case.

Web22 jul. 2024 · Well your original question was "find global minimum of a function", which is a well studied (and very hard) problem in optimization, see e.g. wikipedia. It is well known that gradient descent does not (in general) find the global minimum, so you would need to totally change your method to e.g. simulated annealing or basin hopping.
