Placement options supported by the Optimizer
The Optimizer can be used to place events that:
• Need a location
• Need a location and have a preferred location
• Need a location and must be placed in the same location as the previously listed event
• Can be placed in a location at the same time as other events
• Are related to (are cross-listed with, share meetings with, are back-to-back with) one or more events
The Optimizer also takes all pre-assignments into account in its placement process. See How the Optimizer treats pre-assignments.
How the Optimizer treats pre-assignments
The Optimizer’s treatment of pre-assigned events is confined to a syntax and conflict check. The Optimizer accepts a location
pre-assignment even if:
• The enrollment of the event exceeds the pre-assigned location’s maximum capacity
• The pre-assigned location is blacked out at the times assigned to the event
• The location fill ratio in effect for the pre-assigned location is higher than the fill ratio achieved by the pre-assignment
The Optimizer allows more than one event to be pre-assigned to the same location at the same time if each of the events has been designated as willing to “share space.”
Ideally, the majority of the events you send to the Optimizer should be requesting a location; that is, should not be pre-assigned. Although you may include pre-assigned events, the placement algorithm performs best when it is asked to do most or all of the work of finding appropriate locations for events
