SpiralA new algorithm for non-linear parameter estimation using least squares
Shell Research Ltd., Thornton Research Centre, P.O. Box 1, Chester, UK
A new algorithm for the estimation of parameters in non-linear models is described and its performance is compared with that of other algorithms for minimising sums of squares. The new algorithm is shown to be a significant improvement and has performed well for practical as well as bench-mark problems. Further improvements are under investigation.
