**What it does**
Searches optimized parameter settings for an estimator or pipeline through either exhaustive grid cross validation search or Randomized cross validation search.
please refer to `Scikit-learn model_selection GridSearchCV`_, `Scikit-learn model_selection RandomizedSearchCV`_ and `Tuning hyper-parameters`_.

**Return**

Outputs `cv_results_` from SearchCV in a tabular dataset if no train_test_split, otherwise the test score(s). Besides, Output of the SearchCV object is optional.

**How to choose search patameters grid?**

Please refer to `svm`_, `linear_model`_, `ensemble`_, `naive_bayes`_, `tree`_, `neighbors`_ and `xgboost`_ for estimator parameters.
Refer to `sklearn.preprocessing`_, `feature_selection`_, `decomposition`_, `kernel_approximation`_, `cluster.FeatureAgglomeration`_
and `skrebate`_ for parameter in the pre-processing steps.

**Search parameter list** can be list, numpy array, or distribution. The evaluation of settings supports operations in Math, 
list comprehension, numpy.arange(np_arange), most numpy.random(e.g., np_random_uniform) and some scipy.stats(e.g., scipy_stats_zipf) classes or functions, and others.

Examples:

- [3, 5, 7, 9]

- list(range(50, 1001, 50))

- np_arange(0.01, 1, 0.1)

- np_random_choice(list(range(1, 51)) + [None], size=20)

- scipy_stats_randin(1, 11)

**Estimator / Preprocessor search (additional `:` in the front)**::

     : [sklearn_tree.DecisionTreeRegressor(), sklearn_tree.ExtraTreeRegressor()]

     : [sklearn_feature_selection.SelectKBest(), sklearn_feature_selection.VarianceThreshold(),
        skrebate_ReliefF(), sklearn_preprocessing.RobustScaler()]
