class geneticengine.grammar.metahandlers.lists.ListSizeBetween(min, max)

Bases: geneticengine.grammar.metahandlers.base.MetaHandlerGenerator

ListSizeBetween(a,b) restricts lists to be of length between a and b and implements a special list mutation.

The list of options can be dynamically altered before the grammar extraction

Set.__annotations__[“set”] = Annotated[List[Type], ListSizeBetween(c,d)].

The special list mutation entails three different alterations to the list in question: deletion of a random element;

addition of a random element; and replacement of a random element.

generate(r, g, rec, new_symbol, depth, base_type, ctx)
Parameters:
mutate(r, g, random_node, depth, base_type, current_node, method=pi_grow_method)
Parameters:
crossover(r, g, options, arg, list_type, current_node)
Parameters:

__repr__()
