Finding Maxima, Minima, and Saddle Points with Lagrange Multipliers

Click For Summary
SUMMARY

The discussion focuses on identifying maxima, minima, and saddle points using Lagrange multipliers, specifically addressing the challenge of applying the Bordered Hessian method. The participant expresses difficulty in finding clear criteria for classification of critical points after calculating values for the multipliers. The Bordered Hessian is highlighted as a relevant tool, yet the criteria for its application remain unclear to the user. The conversation concludes with a request for more straightforward resources or explanations regarding this optimization technique.

I'm currently having some trouble, after the procedure of finding the actual values for the multipliers and the points, but how come can I figure out whether which points that I've collected are maxima, minima or just saddle ones. I've taken a look on lots of books, but I can't seem to find something that helps me out with a method that I can apply in general. The closest I reached of something useful was called the 'Bordered Hessian', which was fairly similar to usual optimization, but where I was reading, the criteria was described in kind of a fuzzy way. Can someone help me? Or at least indicate where I can find this in a clear way? Thanks!
