Subject: Re: Armenian approximation
BCC: ellen@snidil.ifi.uio.no

In an email letter of July 9-th, Lotfi Zadeh <zadeh@cs.berkeley.edu> writes:

*****************************************************************************
As we all know, approximation is a matter of degree, and goodness of
approximation is context-dependent. Here is an example.

Two friends, A and B, meet in a cafe in Erevan, capitol of Armenia. The
following exchange ensues:

A: I heard that Armen (a common first name in Armenia) won a car in a
lottery. Is it true?

B: Almost true. A very close approximation.

A: So what happened?

B: Well, in the first place it was not Armen -- it was his brother.
Second, it was not a car -- it was a bicycle. And third, he did not
win it -- it was stolen from him.

A: So it is true.

B: It is.

When someone questions your veracity, you may find it helpful to invoke
the Armenian approximation.


With my warmest regards to all,

Lotfi

I enjoyed Lotfi's story immensely. However, there is no reason why
fuzzy set people should not take it seriously. Maybe we can learn
something from the answers suggested below.

So I would like to ask Lotfi and others:

"If you had been B, what would your final answer
(answer to A's question `So it is true?') be?",

(assuming that B knows that Armen did not win a car).

Please give your answer in both
(I) everyday language, and
(II) with the aid of the membership concept.

With warm regards to all,
Ellen
