We describe a method of using Global Synthesis"R" for finding tolerance-insensitive design forms. By simultaneously
optimizing several design configurations that are nominally identical but differ by tolerance-level perturbations, one
is essentially requesting that the optimizer find solutions that are insensitive to the types of perturbations present.
Global Synthesis is a useful tool for examining a wide range of design forms; when combined with a merit function
that prefers less sensitive solutions, it is particularly useful in exploring the space of tolerance-insensitive design
