Comparison Of Alternating Variable Search And Simple Methods Of Optimisation For Inductively Coupled Plasma Optical Emission And Atomic Fluorescence Spectrometry, Stanley Greenfield, Mahmood S. Salman, Maryanne Thomsen, Julian Tyson

Chemistry Department Faculty Publication Series

The performance of several cyclic alternating variable search (AVS) optimisation methods are compared with two simplex methods with respect to the number of changes of variable required to search a model two-factor response space. The roles of the initial step size and of the variable step size are discussed, and the information produced concerning the shape of the factor space is evaluated. An AVS method which starts with a fixed step size and then changes to a variable step size on second and subsequent cycles is compared with a variable step size simplex for the optimisation of an inductively coupled …
