The constrained optimization problem












1












$begingroup$



  1. I would like to find the minimum value $F(x)=x^{T}Ax$ and $|x|_{2}=1$, where $A$ is symmetric and positive-definite. I know
    that the minimum value is the smallest eigenvalue problem of the
    matrix $A$. However, I want to know that how to use an optimization
    method to find it. The method should be based on an iterative method. Please
    give me the iterative method. I hope this iterative method is
    convergent to the exact solution as quickly as possible. Thank
    you!
