Hello,

I have the following question:

max/min $\displaystyle w=f(x_{1},x_{2},...,x_{n})$ subject to $\displaystyle g(x_{1},x_{2},...,x_{n})=0$ and $\displaystyle a_{1} \leq x_{1} \leq b_{1}, a_{2} \leq x_{2} \leq b_{2},...,a_{n} \leq x_{n} \leq b_{n}$

I need the solution of the above question and also I want to guide me the references related to this problem.
