Main issues: If function f (X) = x1* x1* x1+ x2* x2, the result of a problem considered, the preliminary estimate is that there has been seeking iterative formula weight gradient caused by mold, to be continue to improve, but with the BFGS algorithm in C program calculation, the above problem does not occur, so it is said BFGS algorithm for unconstrained optimization algorithms in one of the most stable
