A New Powell-Type Algorithm and its Analysis

Zhang Suzhong  
In this paper, a new Powell-type algorithm is porposed without derivative. Being directed at unconstrained nonlinear programming problem, it has quadratic conclusive property and entire convergence. And proof is given : To the objective function of consistent convexity the new algorithm is quadratic convergence through the n~2 line searches at every.
