inspyred 1.0.1

示例

下面的示例演示inspyred包的基础知识。在这个 例如，候选解决方案是10位二进制字符串，其十进制值 应最大化：

import random
import time
import inspyred

def generate_binary(random, args):
    bits = args.get('num_bits', 8)
    return [random.choice([0, 1]) for i in range(bits)]

@inspyred.ec.evaluators.evaluator
def evaluate_binary(candidate, args):
    return int("".join([str(c) for c in candidate]), 2)

rand = random.Random()
rand.seed(int(time.time()))
ga = inspyred.ec.GA(rand)
ga.observer = inspyred.ec.observers.stats_observer
ga.terminator = inspyred.ec.terminators.evaluation_termination
final_pop = ga.evolve(evaluator=evaluate_binary,
                      generator=generate_binary,
                      max_evaluations=1000,
                      num_elites=1,
                      pop_size=100,
                      num_bits=10)
final_pop.sort(reverse=True)
for ind in final_pop:
    print(str(ind))

要求

• Requires at least Python 2.6+ or 3+.
• Numpy and Pylab are required for several functions in ^{tt1}$.
• Pylab and Matplotlib are required for several functions in ^{tt2}$.
• Parallel Python (pp) is required if ^{tt3}$ is used.
