G2DBinaryString
– the classical binary string chromosome¶
This representation is a 2D Binary String, the string looks like this matrix:
00101101010 00100011010 00101101010 10100101000
Default Parameters¶

G2DBinaryString
(height, width)¶ G3DBinaryString Class - The 2D Binary String chromosome
Inheritance diagram for
G2DBinaryString.G2DBinaryString
:- Example:
>>> genome = G2DBinaryString.G2DBinaryString(10, 12)
Parameters: - height – the number of rows
- width – the number of columns
-
clearString
()¶ Remove all genes from Genome
-
clone
()¶ Return a new instace copy of the genome
Return type: the G2DBinaryString clone instance
-
copy
(g)¶ Copy genome to ‘g’
- Example:
>>> genome_origin.copy(genome_destination)
Parameters: g – the destination G2DBinaryString instance
-
crossover
= None¶ This is the reproduction function slot, the crossover. You can change the default crossover method using:
genome.crossover.set(Crossovers.G2DBinaryStringXUniform)
-
evaluate
(**args)¶ Called to evaluate genome
Parameters: args – this parameters will be passes to the evaluator
-
evaluator
= None¶ This is the evaluation function slot, you can add a function with the set method:
genome.evaluator.set(eval_func)
-
getFitnessScore
()¶ Get the Fitness Score of the genome
Return type: genome fitness score
-
getHeight
()¶ Return the height (lines) of the List
-
getItem
(x, y)¶ Return the specified gene of List
- Example:
>>> genome.getItem(3, 1) 0
Parameters: - x – the x index, the column
- y – the y index, the row
Return type: the item at x,y position
-
getParam
(key, nvl=None)¶ Gets an internal parameter
- Example:
>>> genome.getParam("rangemax") 100
Note
All the individuals of the population shares this parameters and uses the same instance of this dict.
Parameters: - key – the key of param
- nvl – if the key doesn’t exist, the nvl will be returned
-
getRawScore
()¶ Get the Raw Score of the genome
Return type: genome raw score
-
getSize
()¶ Returns a tuple (height, widht)
- Example:
>>> genome.getSize() (3, 2)
-
getWidth
()¶ Return the width (lines) of the List
-
initializator
= None¶ This is the initialization function of the genome, you can change the default initializator using the function slot:
genome.initializator.set(Initializators.G2DBinaryStringInitializator)
In this example, the initializator
Initializators.G1DBinaryStringInitializator()
will be used to create the initial population.
-
initialize
(**args)¶ Called to initialize genome
Parameters: args – this parameters will be passed to the initializator
-
mutate
(**args)¶ Called to mutate the genome
Parameters: args – this parameters will be passed to the mutator Return type: the number of mutations returned by mutation operator
-
mutator
= None¶ This is the mutator function slot, you can change the default mutator using the slot set function:
genome.mutator.set(Mutators.G2DBinaryStringMutatorSwap)
-
resetStats
()¶ Clear score and fitness of genome
-
resumeString
()¶ Returns a resumed string representation of the Genome
-
setItem
(x, y, value)¶ Set the specified gene of List
- Example:
>>> genome.setItem(3, 1, 0)
Parameters: - x – the x index, the column
- y – the y index, the row
- value – the value (integers 0 or 1)
-
setParams
(**args)¶ Set the internal params
- Example:
>>> genome.setParams(rangemin=0, rangemax=100, gauss_mu=0, gauss_sigma=1)
Note
All the individuals of the population shares this parameters and uses the same instance of this dict.
Parameters: args – this params will saved in every chromosome for genetic op. use
