A Benchmark Study of Optimization Search Algorithms
A thorough study was conducted that benchmarks the efficiency and robustness of several optimization algorithms. In particular, the hybrid adaptive method, SHERPA, in HEEDS MDO, was compared to several existing methods. These algorithms were tested on a broad set of benchmark problems, each of which emphasizes a different set of features commonly found in engineering optimization problems. It was concluded that the SHERPA algorithm is significantly more efficient and robust for these problems than the other methods in the study.
