The time required to perform an image selection model optimization search depends on the number of models being generated/examined. The number of models examined during the search is determined by the selected image selection model categories to search (image filtering, combined z score, group bin) as well as settings specified in "Settings" -> "Image Selection Optimization Settings". If the search space is large, it may take hours to finish the optimization. | The time required to perform a search depends on the number of models being generated/examined.

Search runtime is proportional to the number of evaluating samples. Evaluation methods also influence the search execution time. The 'p-value of Poisson' and 'curve fit residual' methods take approximately the same amount of time. The 'Leave-one-out' method takes longer, and is proportional to the number of evaluating samples. For example, to finish a search using 10 evaluating samples, 'leave-one-out' will take approximately 10-times longer than either 'curve fit residual' or 'p-value of Poisson'. | Search runtime is proportional to the number of evaluating samples.
