import random
from NiaPy.algorithms.basic import MultiStrategyDifferentialEvolution
from NiaPy.task import StoppingTask
from NiaPy.benchmarks import Sphere

#we will run Differential Evolution for 5 independent runs
for i in range(5):
	task = StoppingTask(D=10, nFES=5000, benchmark=Sphere())
	algo = MultiStrategyDifferentialEvolution(NP=50, F=0.5, CR=0.9)
	best = algo.run(task)
	print('%s -> %s' % (best[0], best[1]))
print(algo.getParameters())

The variable algo does not seem to be defined in case the for loop on line 14 is not entered. Are you sure this can never be the case?
