Abstract
This paper investigates, using a sequential unrestrained optimization technique, the computational efficiency of unrestrained minimization algorithms. Minimization algorithms which use no derivatives, first derivatives, and first and second derivatives are used to optimize a variety of structural engineering problems. Derivatives are obtained by direct differentiation and with finite difference formulae. Conclusions are made concerning the efficiency of the finite difference formulae and of the optimization algorithms considered.Keywords
