## Abstract The use of quasiβNewton methods is studied for the solution of the nonlinear finite element equations that arise in the analysis of incompressible fluid flow. An effective procedure for the use of Broyden's method in finite element analysis is presented. The quasiβNewton method is compa
The efficiency of the use of a diagonal approximation to the hessian matrix coupled with a quasi-Newton updating method in MC SCF calculations is examined. In general, satisfactory convergence is obtained provided the CI expansion corresponds to a full valence shell CL
