摘要：
In this paper, by confirming new line-search directions and using Dixon rule to set parameter beta(k), a modified conjugate method for unconstrained optimization problem is presented, which shows all the superior properties of the previous conjugate method, Meanwhile, By establishing compact point sequences, we also prove the global strong convergence property of target function under continuously differentiable condition.
