cmd-ntrf / datalogger.py

Last active December 17, 2015 00:59

DEAP - Proposal for a replacement to the Statistics and EvolutionLogger objects. The Database object combine both object functionalities. It requires numpy for statistics computation.

	try:
	import numpy
	except ImportError:
	import platform
	if platform.python_implementation() == "PyPy":
	import numpypy as numpy
	else:
	raise ImportError("DEAP requires Numpy.")

	from collections import OrderedDict

cmd-ntrf / deap_reg_12args.py

Last active December 14, 2015 07:09

Example of a evaluation function for a trivial symbolic regression problems with 12 inputs using DEAP.

	import operator
	import numpy

	from math import sqrt

	from deap import gp


	# Our dataset is 100 random arrays of 0s and 1s
	# and the function we are trying to find is simply

cmd-ntrf / datalogger.py

Last active December 14, 2015 06:19

Prototype for a DataLogger object based on pandas DataFrame for the DEAP framework. This object would take care of statistics computation and bookeeping along the evolution.

	from collections import defaultdict
	from pandas import DataFrame, concat
	from sys import stdout

	from numpy import random
	from matplotlib import pyplot as plt

	class DataLogger(object):
	def __init__(self, key=None):
	self.key = key

cmd-ntrf / cython_instance_scoop.py

Last active December 14, 2015 01:38

Example of the distribution of an instance method from a Cython class object with SCOOP. It uses the Benchmark class defined by pycec2013 available here : https://bitbucket.org/CmdNtrf/niching-benchmark-cec2013

	import array
	import pycec2013

	from scoop import futures

	if __name__ == "__main__":
	bench = pycec2013.Benchmark(1)
	pop = [array.array('d', [1.0]), array.array('d', [2.0]), array.array('d', [3.0])]
	print(list(futures.map(bench.evaluate, pop)))
	# print(list(map(bench.evaluate, pop)))
