Remarks

Used in the Objectives property.

The scheduling engine supports three search strategies that are specified in the ObjectiveExpression property. A string that contains the search strategy is a parameter to the search methods. The examples show the valid values.

Least Busy - From the list of resources that can perform that specific service, choose the resource that is the least busy and is available at the requested time.

Most Busy - From the list of resources that can perform that specific service, choose the resource that is the busiest and is available at the requested time.

Random - From the list of resources that can perform that specific service, choose any resource that is available at the requested time.

The following table shows the supported values for an evaluation interval.
