CMA-ES covariance precision
Adjust cma-es covariance precision within the CMA-ES search. Start from its initial value while establishing a valid model.
Adjust cma-es covariance precision 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 precision
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
Automatic.
Choices: Automatic, FP64, FP32.
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.
