Dear Prof Diaby,
Yes we are creating a new TSP, where I can mathematically prove the
following 2 points:
1.) The transformed TSP has exactly one optimal tour, even though the
original Generic TSP may have multiple/single optimal tours
2.) The sequence of cities in the optimal tour of the transformed TSP,
is a subset of the sequences of cities of the optimal tours of the
original Generic TSP
Points 1 and 2, correspond to STATEMENT 1 of the original TSP:  "find
the sequence of cities of the optimal tour of the Generic TSP"
In other words, if I give a TSP to Mr. X, and ask Mr. X to produce the
solution to STATEMENT 1, then Mr. X can simply transform the TSP by our
Transformation, and work with the Transformed TSP. The sequence of
cities that Mr. X obtains on the Transformed TSP, will automatically
answer STATEMENT 1 for the original TSP that I gave to Mr. X.
I hope you understood the above paragraph.
We (me & Hofman) will be giving the mathematical proofs for the
abovementioned points 1 and 2, in our paper. But if you wish me to
prove it right now, I am ready to do it within 3 days. Just let me know
if you want to see the proofs immediately.
By the way, if anyone else in the audience wants to see the proofs now,
then pls let me know....I'll write them in three days time, and post
them in this thread. (But I hope you do not ask me to do that work
right away, cos I am Software Engineer now in a company and we will be
very busy for 1 week, but if you still really want me to show the
proofs urgently, I am ready to do it and show it within 3 days time)
Deepak
PS: Regarding feelings, come on Prof Diaby, I am surprised to hear you
say that. No, you haven't hurt my feelings anywhere. And I have a high
regard for the originality of your idea of "flows & layers" of your LP
work, which as I said, needs the proof to the "Final Task for Diaby"
that I posted a few posts above.
