3.5.2. Infinite Streams
Additions in computing Fibonacci numbers.
How many additions are performed when we compute the nth Fibonacci number using the definition of fibs based on the add-streams procedure? Show that the number of additions would be exponentially greater if we had implemented (delay <exp>) simply as (lambda () <exp>), without using the optimization provided by the memo-proc procedure described in section 3.5.1.
