While many design optimization approaches are limited to a small number of continuous design variables, the approach described here leads to a productive search over hundreds of variables at a time. This capability has been implemented in HEEDS (Hierarchical Evolutionary Engineering Design System) Professional. HEEDS was applied to two crashworthiness problems using various search agents to evaluate potential designs with different design variable representations and performance measures.
