Abstract:

A variety of optimization algorithms for engineering synthesis are included in a new general-purpose optimization computer program called ADS-1 Automated Design Synthesis, Version 1. Preliminary testing of all presently available algorithms is conducted utilizing several carefully selected problems of significant size and complexity. These include a problem with 56 design variables and over 3500 inequality constraints. The capabilities and utility of the ADS program coupled with a structural analysis code utilizing finite element techniques is demonstrated and numerical results presented that compare the relative efficiency and reliability of the various optimization algorithms. The number of function and gradient calculations are considered important measures of merit in compring the various algorithms. A comparison of results with another existing optimization computer code is included to document the accuracy and reliability of the ADS program. Preliminary testing of the ADS program demonstrates the flexibility a design engineer would have in selecting an optimization algorithm best suited to solve a particular problem. Author
