Optimization
Search for design-variable values that improve an objective while meeting the chosen constraints.
Search for design-variable values that improve an objective while meeting the chosen constraints.
Where to find it
System Solver workspace; Model Builder → System Solvers
How to use it
Define design controls and an Objective expression, choose minimize or maximize and a method, then set evaluation and convergence limits. Choose Run System Solver, then select the completed solution under Results.
Settings and initial values
| Setting | Initial value |
|---|---|
| Objective expression | No initial value specified |
| Objective evaluate for | Stationary |
| Direction | Minimization |
| Method | GCMMA/MMA |
| Maximum number of model evaluations | 1000 |
| Maximum number of outer iterations | 100 |
| Optimality tolerance | 1e-3 |
| Constraint tolerance | 1e-3 |
Result
Successful runs provide solution data for plots, tables and evaluations in Results.
Troubleshooting
Validate the starting model first. A stopped search is not necessarily an optimum; inspect feasibility, termination reason and the final solved design.
