    Minimum or Maximum value of a multivariate function

    First thank you all for the kind reply. I took a look into Lagrange multipliers. It seems like what I need to use. However I still have one question. I am not sure about how to limit the range for x1,x2, x3, … ,xN I want to find Max/min of: f(x1,x2,…,xn) = f1(x1) + f2(x2) +... +fn(xn)...

    Minimum or Maximum value of a multivariate function

    First thank you for taking your time to take a look at this simple question. And sorry for the informal math language and equations, I hope you guys can understand it. So, depending on the case, I have 2 or 8 simple quadratic functions f(a), f(b), f(c),… f(z). Each a,b,c,…,z have a different...
