Direct search optimisation: deformed configuration methods
Wednesday 1 July 1998 at 15.30, JCMB 6324

Abstract

In this presentation, ideas and ways of construction of deformed configuration methods are described. The deformed configuration methods is a generalisation of the simplex and complex algorithms by Spendley-Hext-Himsworth, Nelder-Mead, M.Box and others. Various versions of configuration mapping, special local optimality criteria whose values are used for assessing possible directions of mapping and choosing the best one, various ways of configuration adaptation are presented. The problem of convergence is also addressed. The assortment of configuration types, mapping versions, local optimality criteria, adaptation procedures and rules for combining them in a way which is most suitable for the user generates a class of the deformed configuration methods.
