Optimization algorithms

Can somebody explain the details about optistruct algorithms

 

1. MFD

2. SQP

3. DUAL

4. DUAL2

5. BIGOPT

 

which is most preferable for respective type of optimization like topology, topography, free size and shape.

Which algorithm is used in the case of a combined optimization (e.g., topology + size optimization)? Are they solved separately using different algorithms?

Adriano_Koga

this is a good question. I can't tell for sure, but i believe when topology is active, then its algorithms will prevail, due to the number of desvars.
