 # Example 15: Sequential Optimization

 Last update: 09.03.2026 

Ex 15: The quick focus and optimization tools are demonstrated. A sample file is opened, and the ‘remove all variables’ and ‘quick focus’ tools are used. Some variables and solves are specified, and a merit function is generated with the merit function wizard. The local, global, and hammer optimizers are each run and closed in sequence.
