Subject: The problem with big-O is one of definitions

Author: Dann Corbit

Date: 15:16:48 05/09/01


Some people are insisting that finite inputs mean O(1).

My insistence is that the big-O behavior should model the difference from n to
n+1 and from n to n-1 (past some point n0).

There are no real algorithms with infinite inputs.   These so-called algorithms
can never terminate.

Because we cannot agree on definitions we can never come to an agreement.  My
definitions are the classiscal defintions used in all the literature.  The
alternative definitions make for interesting debate, but since they have no
value at predictions, they have no practical value.
