CMA-ES covariance

Adjust cma-es covariance within the CMA-ES search. Start from its initial value while establishing a valid model.

Where to find it

System Solver → Optimization → CMA-ES → CMA-ES covariance

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

Diagonal.

Choices: Isotropic, Diagonal, Full.

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.
