well, the total testing already takes half an hour, so doing it 1000 
times isn't really an option. But I'm pretty sure that's not the 
problem. Some example code might clarify:

if I do

[250].each do |sg|

	5.times do

	start = Time.now	
	algorithm(sg)		
	puts Time.now - start	

	end
	
end

the times are (in seconds):

8.853
8.602
7.33
7.281
7.32

but if I do

[1,250].each do |sg|

	5.times do

	start = Time.now	
	algorithm(sg)		
	puts Time.now - start	

	end
	
end

the times are (for the 250 case):

2.804
4.336
3.835
4.036
3.765

Thanks anyway,
