On nonlinear generalized conjugate gradient methods
A nonlinear generalized conjugate gradient method for solving systems of nonlinear equations (including nonsymmetric Jacobian) is presented and analysed. If the Jacobian is positive definite and the Hessian is bounded then the method converges globally to one of the solutions. Also, preconditioned nonlinear methods of three types are discussed. A Newton method coupled with the nonlinear conjugate gradient method is constructed.
