Parent count

Adjust parent count within the CMA-ES search. Start from its initial value while establishing a valid model.

Where to find it

System Solver → Optimization → CMA-ES → Parent count

How to use it

First solve the starting design. Change this control deliberately and compare convergence, evaluations and feasibility with the previous run.

Initial value

null.

Result

Compare the final objective, constraint values, design and termination reason together.

Troubleshooting

Limits on iterations or evaluations can end a search before an optimum is reached. Inspect feasibility and termination reason, then verify the final design with a solve.
