- Abstract
This paper gives a modified Dai-Yuan conjugate gradient algorithm for large- scale nonlinear equations. The presented search direction not only possesses the sufficient descent property but also belongs to a trust region. The new algorithm has the global convergence under appropriate conditions. Numerical results show that this proposed algorithm is more effective than that of the normal method for large scale nonlinear equations.
