class Evolvable(name=None, hints=None, initial_value=MISSING_VALUE, node_transform=MISSING_VALUE, weights=None)[source]¶

Hyper primitive for evolving an arbitrary symbolic object.

Methods:

`custom_decode`(dna)	Decode a DNA whose value is a string of user-defined genome.
`custom_encode`(value)	Encode value to user defined genome.
`first_dna`()	Returns the first DNA of current sub-space.
`mutate`(value[, random_generator])	Returns the next value for a symbolic value.
`mutation_points_and_weights`(value)	Returns mutation points with weights for a symbolic tree.
`random_dna`([random_generator, previous_dna])	Generates a random DNA.

custom_decode(dna)[source]¶

Decode a DNA whose value is a string of user-defined genome.

custom_encode(value)[source]¶

Encode value to user defined genome.

first_dna()[source]¶

Returns the first DNA of current sub-space.

mutate(value, random_generator=None)[source]¶

Returns the next value for a symbolic value.

mutation_points_and_weights(value)[source]¶

Returns mutation points with weights for a symbolic tree.

random_dna(random_generator=None, previous_dna=None)[source]¶

Generates a random DNA.
