Conjugate gradient algorithms are important for solving unconstrained optimization
problems, so that we present in this paper conjugate gradient algorithm depending on
improving conjugate coefficient achieving sufficient descent condition and globa
l
convergence by doing hybrid between the two conjugate coefficients [1] and
[2]. Numerical results show the efficiency of the suggested algorithm after its
application on several standard problems and comparing it with other conjugate gradient
algorithms according to number of iterations, function value and norm of gradient vector.
