Typically More Data, More Time
vThere 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
vThere 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
