    This paper studies the three-term conjugate gradient method forunconstrained optimization. The method includes the classical(two-term) conjugate gradient method and the famous Beale-Powellrestart algorithm as its special forms. Some mild conditions aregiven in this paper, which ensure the global convergence ofgeneral three-term conjugate gradient methods.
