Democritus Algorithms (a.k.a. d8s-algorithms)

Democritus functions^[1] for working with algorithms.

[1] Democritus functions are simple, effective, modular, well-tested, and well-documented Python functions.

We use d8s (pronounced "dee-eights") as an abbreviation for democritus (you can read more about this here).

Installation

pip install d8s-algorithms

Usage

You import the library like:

from d8s_algorithms import *

Once imported, you can use any of the functions listed below.

Functions

• def amb(validation_function: Callable[..., bool], *args: Any) -> Iterable[Any]:
      """."""
  

• def depth_first_traverse(
      data: Any,
      get_children_function: Callable[[Any], Optional[Iterable]],
      *,
      collect_items_function: Optional[Callable[[Any], Any]] = None
  ) -> Iterable[Any]:
      """Traverse the data in a depth-first manner.
  
  The get_children_function specifies how children will be identified from each node of the data.
  The collect_items_function, if provided, allows you to collect items from the data by...
   returning them from the collect_items_function."""
  

• def breadth_first_traverse(
      data: Any,
      get_children_function: Callable[[Any], Optional[Iterable]],
      *,
      collect_items_function: Optional[Callable[[Any], Any]] = None
  ) -> Iterable[Any]:
      """Traverse the data in a breadth-first manner.
  
  The get_children_function specifies how children will be identified from each node of the data.

• def genetic_algorithm_run(
      data: Iterable[Any],
      scoring_function: Callable[[Any], Union[int, float]],
      selection_function: Callable[[Dict[Any, Union[int, float]]], Iterable[Any]],
      mutation_function: Callable[[Iterable[Any]], Iterable[Any]],

• def genetic_algorithm_best_mutation_function(
      starting_values: Iterable[Any],
      generations: int,
      scoring_function: Callable[[Any], Union[int, float]],
      mutation_functions: List[Callable[[Any], Any]],
  ):
      """Find the best mutation function.
  
  The best function is the one which produces values from the starting values...
   that score the highest (as measured by the scoring_function) after generations."""
