Create Sum Optimization from Point Optimization Output

Many users employ a point optimization to find good initial values for a sum optimization. To make this workflow easier and faster, you can use a utility to create a sum optimization from your point optimization output.

From your point optimization output node, select Solution > Create Sum Optimization.

CAGE creates an optimization (called Sum_myOptimizationName). The optimization has these characteristics:

• The objective matches your original optimization but converted to a sum objective.

• The new optimization has identical constraints to your original optimization. Edit or add to these as usual if desired.

• Your original fixed and optimization variables are converted to a sum optimization (a single run with multiple values).

  • The new optimization uses only accepted solutions from your original optimization output (all runs with a selected Accept check box).

  • Therefore, the number of accepted solutions you had in the original optimization determines the number of values within the sum optimization run.

• The free variable initial values and fixed variable values are populated from your point optimal results (accepted solutions only).

• The fixed variables have a Weights column with every value set to 1.

If you rerun point optimizations that have associated sum optimizations, the Model-Based Calibration Toolbox™ can update and rerun the sum optimization with the point optimization results. The Model-Based Calibration Toolbox uses the existing sum optimization constraints when it reruns the optimization. Previously, the Model-Based Calibration Toolbox created a sum optimization.
