A method for obtaining a global minimizer of the problem: minimize f(x) s.t. L equal to or less than X equal to or greater than U is presented when f(x) has kth order continuous derivatives. subintervals are found on which certain derivatives have constant sign. An upward process then...
Suppose you have one-layer-two-dimension network, then the image of F may look like this: When we talk about training, we are actually talking about finding the w which makes the minimal e. In another word, we are searching the minimum of a function. To train is to search. So, you ...
I'm fairly new to R and am trying to find the minimum date/time for each value of an ID number. Below is an example of the data I'm working with ID DATE111/24/1212:51111/24/1212:52111/241212:53211/27/122:52211/24/1212:53 ...
A GENERAL algorithm for finding the absolute minimum of a function to a given accuracy is described and special aspects of its application are illustrated by examples involving functions of one or more variables, satisfying a Lipschitz condition....

I am practising some old exams for my calculus class, and got stuck on a Lagrange problem I can't seem to figure out entirely. I have a function f(x,y)=2x2−x4+y2f(x,y)=2x2−x4+y2 and the question is to find the maxima and minima of ff on the curve x4+y2=4x4...
