Abstract:	This paper present a new class of nonmonotone trust region algorithms based on conic model for unconstrained optimization.The class of nonmonotone strust region algorithms based on quadratic model is a special example of the new algorithms.Global and Q-quadratic convergence are proved under certain conditions.

Keywords:	Unconstrained optimization Conic model Nonmonotone trust region algorithms Global convergence Q-quadratic convergence
