Some observations on the generalized conjugate gradient method,As we have seen, if systems of the form . are “easy” to solve, then GCG is better than CSP. If not, then CSP is superior. Of course, it is not clear that either method is the best possible for this class of problems.

A linear uncoupling numerical scheme for the nonlinear coupled thermoelastodynamics equations,A numerical scheme for computing approximate solutions to the non-linear equations of coupled thermoelastodynamics is proposed. The discretization is made in such a way that the algebraic system to be solved at each time level is a linear one, the displacement and temperature fields being uncoupled for the calculations.

A dual solution procedure for quadratic stochastic programs with simple recourse,adratic recourse costs — that is essentially a deterministic quadratic program except for some simple stochastic upper bounds. We then describe a solution procedure for problems of this type based on a finite element representation of the dual variables.

Piecewise nonlinear homotopies,n of this work is to elaborate homotopy algorithms for solving nonlinear programming problems. The application of the results, given in this paper, to optimization problems will be published elsewhere.

A multifrontal approach for solving sparse linear equations,.We illustrate our remarks by examining the performance of a Harwell code based on this approach. In particular, we show that the simple inner loop of such codes performs well on machines capable of vectorization.
