First order optimality conditions
WebThe first order optimality condition translates the problem of identifying a function’s minimum points into the task of solving a system of N first order equations. There are however two problems with the first order characterization of minima. What is optimality condition in LPP? http://liberzon.csl.illinois.edu/teaching/cvoc/node7.html

So the rate of change of f in respect to both x and y is naught at a critical point. The second-order conditions at a critical point that I have in my book are of the following form: A point (a,b) is a maximum if f x x f y y − f x y 2 > 0 and f x x ...
