class_docstr: Class providing the core functionality of a parameter, aka
  value, internal/model parameters, mutation, recombination
  and additional features such as shared random state,
  constraint check, hashes, generation and naming.
  The value field should sent to the function to optimize.
  
  Example
  -------
  >>> ng.p.Array(shape=(2,)).value
  array([0., 0.])
docstr: Generation of the parameter (children are current generation + 1)
docstr_tok: ["Generation","of","the","parameter","(","children","are","current","generation","+","1",")"]
code: def generation(self) -> int:
      """Generation of the parameter (children are current generation + 1)"""
      return self._generation
