Equivalence is in the Eye of the Beholder
In a recent provocative paper, Lamport points out "the insubstantiality of
processes" by proving the equivalence of two different decompositions of the
same intuitive algorithm by means of temporal formulas. We point out that the
correct equivalence of algorithms is itself in the eye of the beholder. We
discuss a number of related issues and, in particular, whether algorithms can
be proved equivalent directly.Comment: See also the ASM web site at http://www.eecs.umich.edu/gasm
