gaft.components.decimal_individual

Definition of individual class with decimal encoding.

class gaft.components.decimal_individual.DecimalIndividual(ranges, eps=0.001)

Bases: gaft.components.individual.IndividualBase

Individual with decimal encoding.

Parameters:

• ranges (tuple list) – value ranges for all entries in solution.
• eps (float or float list (with the same length with ranges)) – decrete precisions for binary encoding, default is 0.001.

clone()

Clone a new individual from current one.

decode()

Decode gene sequence to decimal solution

encode()

Encode solution to gene sequence

init(chromsome=None, solution=None)

Initialize the individual by providing chromsome or solution.

Parameters:

• chromsome (list of (float / int)) – chromesome sequence for the individual
• solution (list of float) – the variable vector of the target function.

Note

If both chromsome and solution are provided, only the chromsome would be used. If neither is provided, individual would be initialized randomly.
