Claim One:
1. A method of filtering a trade space in a constraint management system (CMS) to determine a Pareto envelope, the CMS having a network of nodes, the method comprising: representing computational paths from user-selected input parameters to user-selected output parameters using an automatic nonlinear equation solver; representing a trade space as one or more compound-valued variables embedded in the network of nodes, the trade space including a specification of user-selected input variables and user-selected output variables; automatically selecting a subset of equality constraints that form the computational paths from the user-selected input parameters to the user-selected output parameters; computing the values of the user-selected output variables given the values of the user-selected input variables; generating a data set representing the trade space; filtering the trade space to determine the Pareto envelope; automatically varying the trade space and associated Pareto envelope as auxiliary input parameters are varied; and back-solving for one or more user-selected auxiliary input parameters so that user-selected scalar attributes of the trade space achieve user-specified values.
