1. The first step is to open Solutions | ALICE and click What if.

2. Click to expand your optimization preset menu.

3. Optimize using an existing solution to build on a previous scenario or set a new one.

4. Set a maximum duration in days.
Note: if the max duration is not mathematically feasible based on your constraint you will receive an infeasibility and will need to modify constraints to get a feasible solution.

5. Set the run time for your simulation.
10 minutes is the default
5 minutes can be helpful if you're in a time crunch or need to make a minor change 
more than 10 minutes is only recommended for highly complex projects
60 min is the max run time  

6. Select up to 2 optimization presets for best results.

7. Click Run scenario.
