Those dazzled by his breakthroughs in factoring and FLT who are eager to
see what his next breakthrough will be might find
comp.lang.java.programmer interesting. JSH has started posting there
about his new project: solving the traveling salesman problem.

Solving for 10 million cities would not be much faster in optimized
assembly than in Java :-)
Unless JSH has made /another/ break through. |

Yes, JSH has made another break through. He's going to reduce the
number of cities in the problem by reducing the cities to radioactive
rubble. Oh, wait, that's GWB's solution.
Actually, I think the traveling salesman problem needs to be re-worded
so for N cities it also involves avoiding N jealous husbands. |

I am sure JSH can optomize two cities, but his discovery will not be able to
do 3 or more. |

So far in this thread there's been a reference to farmers' daughters, and
to jealous husbands. �Evidently there are some aspects to the travelling
salesman problem I'm not aware of. �Could anyone enlighten me?
There were these 3 traveling salesmen:
Jimmy, the fertilizer salesman
Stevie, the seed salesman
Harry, the tractor salesman
They traveled together to save money.
One day, they had a rough time convincing a
farmer to buy their products. By the time the
deals were closed, the sun had already set
and they lamented being able to find a place
to stay for the night.
The farmer offered them his barn to sleep in
as the only beds in his house were occupied by
him and his wife and that of his young daughter,
Betty-Lou. They gladly accept knowing how far
they are from the nearest town.
In the middle of the night, Harry leaves the
hay loft and mkes a run to the outhouse.
Only to find Betty-Lou sitting there when he
opens the door.
The two return to the hay loft, nudge, nudge.
Next morning at the crack of dawn, the farmer
comes out to the barn and informs the salesmen
his wife is whipping up a big batch of hotcakes
and if they go pick some fruit while he milks the
cows, they can all sit down to a nice hearty
breakfast.
Harry arrives back at the kitchen first with a big
basket of blueberries.
Only to find the farmer pointing a cocked,
double-barrel shotgun at him!
"Take those bleberries and shove them up your ass!",
he orders.
When Stevie arrives with a basket of cherries,
he, too, is forced to shove them up his ass.
Stevie and Harry glance at each other and begin
to snicker. "What's so damned funny?", demands
the farmer.
In unison, they reply:
"Jimmy's out picking watermelons."

I am not an expert, and I certainly don't think that he should be an
object so degraded that one can only laugh at him.
In any case, my personal evaluation is that
a) He is looking for P = NP.
b) He has discovered (or will shortly) a version of bidirectional search
for TSP that he is going to try to tweak to get P = NP (which should be
fruitless; you can read my full response to see why).
c) He will, alas, not find that P = NP. I have some experience, maybe
more than he does, on the area; I believe P = NP for various personal
reasons, but I also don't believe I or anyone else will solve it for at
least 50 years.
In short, the same old: going down fruitless paths for research in an
area where existing results are good enough for general use.
Actually, Jimmy is probably better off on
a fruitless path (see my explanation of the
Traveling Slaesman Problem to Hendrik Boom). |

It's an issue of ridiculous time vs. ludicrous time. |

And JSH might claim that he could do better than anyone else at solving
special
instances of the Halting Problem, and could compute Omega to a thousand
digits in about a month... |

perhaps the problem he should be working on is how to construct an
optimal posting schedule across newsgroups to minimize ridicule. this
would presumably be a function of membership expertise, turnover, and
overlap, as well as overall traffic volume - and of course the subject
would have to be within JSH's preferred domain of crankery.
evidently he hasn't solved that one yet...

What did Steve and Jimmy do? Seems like only Harry tasted the fruit of
the vine, so to speak ;>).
