Title: The theoretical aspects of the optimal fixedpoint

Abstract: In thls paper we define a new type of fixedpoint of recursive
definitions and investigate some of its properties. This
optimal fixedpoint (which always uniquely exists) contains,
in some sense, the maximal amount of "interesting"
information which can be extracted from the recursive
definition, and it may be strictly more defined than the
program's least fixedpoint. This fixedpoint can be the basis
for assigning a new semantics to recursive programs.
This is a modified and extended version of part 1 of a paper
presented at the Symposium on Theory of Computing,
Albuquerque, New Mexico (May 1975).
