Initial step size
Adjust initial step size within the CMA-ES search. Start from its initial value while establishing a valid model.
Adjust initial step size within the CMA-ES search. Start from its initial value while establishing a valid model.
Where to find it
System Solver → Optimization → CMA-ES → Initial step size
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
0.25.
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.
