document: Development of visual design steering as an aid in large-scale multidisciplinary design optimization . I. Method development A modified paradigm of computational steering -LRB- CS -RRB- , termed visual design steering -LRB- VDS -RRB- , is developed in this paper . The VDS paradigm is applied to optimal design problems to provide a means for capturing and enabling designer insights . VDS allows a designer to make decisions before , during or after an analysis or optimization via a visual environment , in order to effectively steer the solution process . The objective of VDS is to obtain a better solution in less time through the use of designer knowledge and expertise . Using visual representations of complex systems in this manner enables human experience and judgement to be incorporated into the optimal design process at appropriate steps , rather than having traditional black box solvers return solutions from a prescribed input set . Part I of this paper focuses on the research issues pertaining to the Graph Morphing visualization method created to represent an n-dimensional optimization problem using 2-dimensional and 3-dimensional visualizations . Part II investigates the implementation of the VDS paradigm , using the graph morphing approach , to improve an optimal design process . Specifically , the following issues are addressed : impact of design variable changes on the optimal design space ; identification of possible constraint redundancies ; impact of constraint tolerances on the optimal solution : and smoothness of the objective function contours . It is demonstrated that graph morphing can effectively reduce the complexity and computational time associated with some optimization problems
