Running the Optimizer

1. In the 25Live Administration Utility, click the Optimizer tab, then click the Manage Runs tab to open the Manage Schedule25 Optimizer Runs page.

2. Highlight the run you want, and click Start to go to the Optimizing Run page. If this is the first time the run you selected has been executed, click Run Prepare to perform the input data Prepare step of the run. You see the progress of the input data preparation step in a separate window. Depending on the number of assignment requests, this step may take a number of minutes to complete.

Note: You can only execute runs you’ve created. To execute a run created by someone else, you must first create a copy of their run (see Editing or copying a run).

3. Correct any input data errors and/or warnings (click the “about this error” link next to any error or warning for information about it):

• If fatal errors are reported (shown in red), correct them as indicated below. You can’t perform the Optimize step of the run (that is, run the placement algorithm) until all fatal errors have been corrected. You receive a fatal error under any of the following conditions:


If...	Do this...
There was an error running a search, your selected location and/or event search didn’t yield any results, or your event search results contained only pre-assignments	Modify and rerun the search in 25Live. See Creating, running, and saving a location search and Creating, running, and saving an event search.
Your Schedule25 Optimizer license is missing or expired	See your Series25 System Administrator for assistance.

• If non-fatal errors are reported, correct the associated records. Such errors do not prevent you from performing the Optimize step of the run, but may have unwanted effects on run results.

For example, if you receive this error: “x rooms have zero capacity” you could access each of those locations in 25Live (by clicking the “show rooms” link and then the link of each location) and entering its maximum capacity.

You receive a non-fatal error under any of the following conditions:

• There are locations in your location search results that don’t have a maximum capacity defined or where the maximum capacity is 0 (zero).

• There are organizations associated with the events in your event search results that don’t have a first choice partition preference defined or have no partition preferences defined.

• There are events in your event search results that have feature requirements that are not present in any of the locations in your location search results.

• If warnings are displayed, determine which of the associated events and/or organizations you wish you correct (if any), and correct them accordingly. You receive a warning under any of the following conditions:

• There are organizations associated with the events in your event search results that have errors.


	Be aware that if you choose to correct events in 25Live, the next time those events are imported into your Series25 environment from your SIS, those corrections will be overwritten by the values in the equivalent fields in your SIS.

4. Click Run Prepare to rerun the Prepare step to ensure that you’ve corrected the errors and warnings.

5. Click the Optimize tab, then click Optimize to run the Optimizer algorithm and report a summary of optimization results as shown below.

6. To see the Optimizer run report which includes rooms from your location search that are still available after the run, click View Report, then open the Excel file (see Optimizer run report).
