Typically More Data, More Time
	v There are much more complicated computations ; A quadratic computation takes 4 times the time when there is twice the data, 9x time for triple the data, etc. ; Checking to see if an employee has the same address as another employee might be an example v There are even more complex computations ... ; “Exponential problems” require double the time when adding just one more data value ; “Try all combinations” is a typical example
		The “knapsack problem” concerns packing different sized items to fit in a give space … need to fill maximum items
				Fast solutions for the knapsack problem would exist if computers could correctly guess
