evolution_strategy='best2'		#evolution strategy can be 'best1', 'best2', 'rand1' and 'rand2'. Best uses the best point, rand uses a random one, the number indicates the number of directions added.
population_size=10				#a multiplier for the population size of a generation
mutation_scale=(0.4, 1.1)		#the minimum and maximum value for the mutation scale factor. Each generation is randomly selected from this. Each value must be between 0 and 2.
cross_over_probability=0.8     	#the probability a parameter will be resampled during a mutation in a new generation
restart_tolerance=0.02			#the fraction the standard deviation in the costs of the population must reduce from the initial sample, before the search is restarted.
