What is pseudopolynomial time? How does it differ from polynomial time?
...r of bits required to represent W

How is this fibonacci-function memoized?
...t one.
It's essentially a clever and low-rent form of dynamic programming based on GHC's lazy semantics. I think the standard only specifies that it has to be non-strict, so a compliant compiler could potentially compile this code to not memoize. However, in practice, every reasonable compiler is g...
