# num_experiments

#### `num_experiments: <int>` (Optional)

## Description

The number of experiments to run during AutoML. AutoML selects hyperparameter configurations via random sampling without replacement (best effort). If the candidate search space is smaller than `num_experiments`, or constraints/pruning reduce the viable pool, Kumo may reuse a configuration or run fewer unique experiments.

* `num_experiments` must be `> 0`.
