Abstract

This presentation introduces a new evolutionary algorithm that can be used to find starting values (SVs)for nonlinear regression (NLR) problems. The method is called a Stochastic Funnel Algorithm (SFA). The SFA is introduced through its operation in the SSE/parameter space of a NLR model. The SFA uses a relaxed trust region in the log10 space of the parameters of an NLR model. The SFA takes explicit advantage of the general shape of the Sum-of-Squares Error (SSE) of a data/model set to explore and exploit that space and eventually converge to the region of the best parameter estimates.
