heal.abstract	The convergence properties of a number of different versions of the conjugate gradient algorithm are tested when applied to the solution of sets of nonlinear equations with a sparse, symmetric, and positive-definite Jacobian as encountered in nonlinear structural analysis. Consideration is given, on the convergence properties of the algorithm, to the effect of the one-variable minimization routine and its accuracy as well as to the replacement of the one-variable minimization by a stability test. The evaluation of the performance of the algorithms is realized on a variety of test problems combining different structural characteristics. The programming has been made on an equitable basis insuring reliable criteria for comparison. © 1986.	en
