Grid Pooler

Creates exhaustive pool from discrete values using a Cartesian product of sets.

Example

To illustrate the concept of an exhaustive pool, let's consider a situation where a certain condition is defined by two variables: \(x_{1}\) and \(x_{2}\). The variable \(x_{1}\) can take on the values of 1, 2, or 3, while \(x_{2}\) can adopt the values of 4, 5, or 6.

\(x_{1}\)	\(x_{2}\)
1	4
2	5
3	6

This means that there are various combinations that these variables can form, thereby creating a comprehensive set or "exhaustive pool" of possibilities.

	4	5	6
1	(1,4)	(1,5)	(1,6)
2	(2,4)	(2,5)	(2,6)
3	(3,4)	(3,5)	(3,6)

Example Code

from autora.experimentalist.grid import grid_pool
from autora.variable import Variable, VariableCollection

iv_1 = Variable(allowed_values=[1, 2, 3])
iv_2 = Variable(allowed_values=[4, 5, 6])
variables = VariableCollection(independent_variables=[iv_1, iv_2])

pool = grid_pool(variables)
