THE COMPOUNDING OF GRADIENT ERROR IN THE METHOD OF PARALLEL TANGENTS,
Abstract
The problem of determining by successive experi ments the input conditions which optimize a response is considered. An investigation is made of the role of observational error on the performance of two competing iterative methods. A general description of the contents is followed by a presentation of terminology used. The two path methods considered, steepest descent and steepest descent partan are described. A gradient error is introduced. Certain restric tive assumptions are made, and equations are developed which represent a response in terms of a surface, contour, starting point, and error. A criterion which measures performance is devel oped, and then averaged over a collection of starting points and errors for each competing method. The numerical results of representative inputs considered are given.
