# Starting Search in Auto Mode

## Start Search

Click Start to begin the search. The progress of the search will be displayed at the bottom of the page. Once the search begins, the utility will indicate the search progress for each parameter combination at the lower pane of the screen.

Note: The length of a test is dependent upon the GPU (and number of GPUs), the number of parameters, the number of parameter settings per parameter, the number of images, and the number of test runs. Each additional set of parameters and values will cause the execution time of the experiment to run exponentially longer.

### Step 1 - Search for Network Model parameters and Patch Size (Red Analyze High Detail)

Unlike the manual mode, the search in Auto mode consists of 2 steps. The first step examines only Network Model and Patch Size (Red Analyze High Detail) parameters to determine their best values. If you entered single values for Network Model and Patch Size or no values for them, those single values or the default values will be used as their best values and the first step will be skipped. Note that you cannot pause a search while it is on its first step. Also, if you stop a search on its first step, you cannot get the results of searches completed so far.

Note: For Green Classify High Detail, if the software decides to resize the views, the change occurs before the first step and the system uses the new sizes consistently in every search throughout the second step.

The First Step Goes Through Every Combination of Network Model parameters and Patch Sizes (Red Analyze High Detail)

### Step 2 - Search for Perturbation parameters

Standing on the best values of Network Model and Patch Size found, the second step goes over the other parameters. Unlike the manual mode, the progress pane displays only the most performing parameter combinations and their numbers are the values you entered in Number of Models.

The Second Step Goes Through Perturbation parameters, Pruning Searches of Unpromising Parameter Combinations for Faster Search.

While a search is in progress, you can temporarily halt the search by clicking Pause. If you click Start again, the search will be resumed from the paused point. Once the search is completed, you can review the results to determine the best combination of parameters on the Results tab. If you click Pause or Stop when a search in progress is on its second step, you can check the results generated so far on the Results tab.
