| Abstract | ||
| New hyperbolic model different from the quadratic ones is proposed for solving unconstrained optimization problems which modify the classical conjugate gradient method. This new model was compared with established methods over a variety of standard non-linear test functions. The numerical results show that the use of non-quadratic model is beneficial in most of the problems considered especially when the dimensional of the problems increases. | ||
