Optimizer Simulation Transformations

When running an Optimizer simulation in X25 Analytics, you might want to apply transformations to the simulation's event and/or location lists. Transformations are hypothetical data changes that apply only to the snapshot data in the context of the simulation and are not carried over to 25Live.

You can apply specific transformations when creating an Optimizer list. Each transformation can be applied to a given list only once. Most transformations have options that must be configured, as described in the tables below.

To Add or Edit List Transformations

1. Navigate to Transforms

In X25 Analytics, select Transforms from the left sidebar under the Projects tab.

2. Select a List to Transform

Use the List Mode drop-down to choose to manage event or location lists.
Select the list you want to edit.
Click Apply Transformation from the buttons on the top.

3. Make a Transformation Selections

In the Edit Transforms window that appears, select the desired transformation from the drop-down.
Click the + button to add the selected transformation to the list.
Expand the transformation window by clicking the down arrow to the right of its name.
Set the options for the transformation.

4. Save

Click Done when finished.

Event List Transformations

Transformation	Options	Effect
Meeting Pattern	Select from the list of predefined time mappings	Alters the start time, end time, and days of the week of every class in the list according to the mappings in the list.
Remove Assignments	None	Removes any location assignments of the classes (from 25Live data) prior to the Optimizer run. If your snapshot includes a term that has already been fully scheduled in 25Live, it's likely you'll use this transformation on every event list you create. Otherwise, there's nothing for the Optimizer to place!
Add Preferences	Select from a list of location features	Adds selected location feature preferences to all classes in the list. These are treated as requirements for placement by the Optimizer.
Remove Preferences	Select from a list of location features	Removes selected location feature preferences from all classes in the list, if they are present.
Alter Enrollment	Increase or decrease Value Percent or attendees	Adjusts the headcount of every class in the list by a fixed value or a percentage.
Bind Back to Back	Enrollment variation Max minutes between	Treats classes with the same instructor as if they are bound (requiring the same location assignment). Ignores classes if there is too much time between them or if their headcounts differ too much.

Location List Transformations

Transformation	Options	Effect
Alter Capacity	Increase or decrease Value Percent or seats	Adjusts the capacity of every location in the list by a fixed value or a percentage.
Alter Partitions	Select from a list of location partitions	Sets the partition of each location in the list to the selection.
Add Features	Select from the list of location features	Adds selected location features to all locations in the list.
Remove Features	Select from a list of location features	Removes selected location features from all locations in the list if they are present.
Alter Fill Ratios	Increase, decrease, or set Value	Adjusts the fill ratio by a fixed value or sets it to that value for all locations in the list. Classes will not be placed in a location if their seat utilization would be lower than the location's fill ratio.
