Parameters
----------
scenarios : numpy.array
Contain the input scenarios.
The columns representing the individual scenarios
The rows are the vector of values in each scenario
number_of_reduced_scenarios : int
final number of scenarios that
the reduced scenarios contain.
If number of scenarios is equal to or greater than the input scenarios,
then the original input scenario set is returned as the reduced set
probability : numpy.array (default=None)
probability is a numpy.array with length equal to number of scenarios.
if probability is not defined, all scenarios get equal probabilities
Returns
-------
reduced_scenarios : numpy.array
reduced set of scenarios
reduced_probability : numpy.array
probability of reduced set of scenarios
reduced_scenario_set : list
scenario numbers of reduced set of scenarios
Example
-------
Scenario reduction can be performed as shown below::
>>> import numpy as np

test | simultaneous_backward_reduction | Simultaneous backward reduction algorithm
Parameters
----------
scenarios : numpy.array
Contain the input scenarios.
The columns representing the individual scenarios
The rows are the vector of values in each scenario
number_of_reduced_scenarios : int
final number of scenarios that
the reduced scenarios contain.
If number of scenarios is equal to or greater than the input scenarios,
then the original input scenario set is returned as the reduced set
probability : numpy.array (default=None)
probability is a numpy.array with length equal to number of scenarios.
if probability is not defined, all scenarios get equal probabilities
Returns
-------
reduced_scenarios : numpy.array
reduced set of scenarios
reduced_probability : numpy.array
probability of reduced set of scenarios
reduced_scenario_set : list
scenario numbers of reduced set of scenarios
Example
-------
Scenario reduction can be performed as shown below::
>>> import numpy as np
>>> import random
>>> scenarios = np.array([[random.randint(500,1000) for i in range(0,24)],

By default, this will perform a `term` search. If you want to search
by phrase, use the `phrase` keyword argument. What's the difference
between `term` and `phrase` searches? Simple: a term search will
return results matching any words given, whereas a phrase search will
match all words.
Note that this method is a GiphyImage generator that
automatically handles api paging. Optionally accepts a limit that will
terminate the generation after a specified number of results have been
yielded. This defaults to 25 results; a None implies no limit
