10/25 Do any websites (ala Mapquest or Etak) approximate The Travelling
Salesman Problem? I went to visit 15 condos in San Diego today, and
it was a bitch using Yahoo+Thomas guide to map out a semi-ideal
route. I don't need an optimum path, just a first order approximation.
I don't think I'll ever need more than 20 addresses at once either...
I'd pay $.99 every time I need this feature...
\- the emacs mapquest interface can do that.
do M-x mapquest-metropolis --psb
\_ I knew emacs was cool. I didn't know how cool until now.
\_ Is this the real psb? Because that didn't work for me.
\- you need the Los Alamos Simulated Annealing emacs lisp
package. --psb
\- that was not the real psb. ok tnx. -psb
\- no, that was me. the immediately above is not me. --psb
\_ You mean it was !psb, right psb?
\_ What is the "Travelling Salesman Problem"?
\_ No cookie.
\_ find out the route which traverses all cities with the minimum
distance.
\_ Just use the thomas guide. It's at 1200dpi. mapquest is at
whatever resolution your monitor is at.
\_ you're a moron
\_ My point is that there is WAY more detail on a single
thomas guide page than on 30 yahoo maps put together.
\_ Okay, get a Real map (Thomas or AAA) big enough
to fit all the points. Then put a dot sticker at
each address and use your highly evolved
mamalian intellect to see patterns. Connect the
dots. Do you have a beter solution?
dots. It's not perfect, but do you have a solution?
\_ You're still a moron. The OP wants to know how to get
from point A -> B -> ... -> Z in an optimal manner.
\_ Hey person with Etak friend... can you ask them if they have
anything like that. Or is there any API where a 3rd party could
program that feature?
\_ I can't wait until <DEAD>maps.google.com<DEAD>... google would support it!
\_ Even your first order solution will be near useless because of the
ugly realities of traffic patterns, highway congestion, etc. I'll
get 30 miles down a freeway at 3am faster than you'll get 10 miles
down a dirt road at noon. Just use some common sense.
\- the algorithms allow for weights ... of coure knowing what
weights to plug in in a little tricky. i am not sure the
algorithms i know of can deal with "asymmetric" weights ...
usually on a metric the distance from d(x,y) = d(y,x) which
clearly isnt true with traffic flows if we care about time.
although some LA trunks seem to be equally congested in both
directions. --psb
\_ When you're taking city streets within a 5 mile range, it
isn't that big of a difference. Or at least not in my case.
\_ isn't there a way to plot multiple locations at once? just do that
and do a rough aproximation yourself. the above poster is right...
small distance details will be less important than type of road,
traffic, etc. But just plotting them all on one map should be
enough for you to use common sense to plan a route.
\_ This would work. Which service supports this (yahoo doesn't)? |

10/27 by 03 repugs will control the white house, the senate
and the house, as well as majority of the governorships.
\_ because you always look smart using cutesy little ad hominen when
discussing your political opposition. you wouldn't look like an
ignorant bratty child. nope, not at all. have a nice day.
\_ And responding in kind makes you look so much more mature. |

10/28 So why is it that gas prices in the bay area (any city, any station)
are higher and sometimes *much* higher than the isolated, zero
competition stations on the I-5? What's the excuse for that BS?
\_ gas/food/utility is a small fraction of your housing expense.
Why don't anyone bitch about that?
\_ They've admitted all along that gas prices are based in part
on income levels of the zip code. Then throw in the cost of
doing business in the bay area, and there you are.
\_ Buy a hybrid
\_ My first thought would be land expense. Also, how about taxes?
There might be far higher taxes in urban areas. --PeterM
\_ When I drove the I5 in '89, gas was about 50% higher on the I5
than here. I'm not aware of any changes in the tax rates that
would account for 10% lower on the I5 now.
would account for 10% lower on I-5 now.
\_ supply and demand. No matter how expensive the gas is your wealthy
next-door-retired-HP/IBM/Intel-guy-who-worked-here-for-30-years
when-a-3000-sq-ft-house-in-SJ-was-only-$80,000 will still pay for
the gas, lowering competition. That's why BA sucks. Let's all
leave! I did and I'm happy.
\_ amen on that, man. fuck the bay area. i pay 25% less in gas
or so, *and* i walk to work every day from a decent home.
\_ When the next gas is 30 to 60 miles and your typical driver has
another 200+ miles to go, I'd say supply is low and demand is
high on the I5. I think you might have something with the "Bay
Area people are just stupid" concent, though.
\_ More people live here than travel along I5. Why is demand
necessarily high? Besides, people are more inclined to be
picky if they know they are going to spend a large sum on
gas in the next few hours.
\_ bullshit. it's collusion.
\_ a Hydrogen/Solar economy is inevitable.
\- There are two major variables you can collpase this to
per occam to get good quality explanation: 1. REGULATION
2. COMPETITION. The regulations explain why production
costs in califnornia are higher and (surprise) explain why
costs of gas are high all over CA. 2. As for why gas prices
are higher in Bay Area than Los Angles, that is largely
competition [LA has more gas stations per unit area].
A third factor, production costs [I am including shipping
from production site, to refining site, refining costs,
jobber costs,and finally shipping to pump], probably
contributes some ... large diameter pipelines are the cheapest
way to move oil ... and there is no lg diameter pipeline to
CA ... however supertankers are actually pretty cheep, and
if this were the largest contributing factor, you would think
Hawaii would have the most expensive gas, but SF started to
pass Hawaii a little while back. You can discover this and
more via emacs M-x analyze-local-petrolium-mkt. You may
need to do a (setq calendar-latitude +38.9)
(setq calendar-longitude -122.25)
guess what, the Bay and the I5 are both in CA and suffer
first, however. ok tnx, --psb
\_ all of which fails to address the question, which is
"why are gas prices higher in the Bay Area than on I-5",
guess what, the Bay and I-5 are both in CA and suffer
from the same regulation. And as for competition,
it always seems to me that gas stations on I-5 are
crowded all the time, while gas stations in the Bay
are not so busy. If anything, it argues for economies
of scale on I-5 vs local stations in the Bay.
What about land expense, taxation, and lower labor costs,
also?
\_ Are you stupid or just stupid? Try looking into the
regulations before presuming they're statewide.
\_ I was criticizing psb, who only mentioned CA
regulations. He made no claims about regional
regulation.
\_ criticizing on what he _didn't_ say... train
be diff in the i-5 case. what you need to look at
harder.
\_ Land is cheap along I-5, but expensive in the BA.
\- "crowded" is not the measure of competition.
the franchise terms and jobber set ups may also
isnt a matter of competition. if the i5 gas station
be diff in I-5 case. what you need to look at
are profit margins. a higher price can reflect
either higher costs, perceived product differen-
tiation or rents/mkt/power/less competition.
if the price is higher due to higher costs, that
isnt a matter of competition. if an I-5 gas station
has a larger profit margin, that may be an
interesting phenomenon looking for an explanation.
the mcdonalds outside the grand canyon has really
high prices. is it because they have a monopoly
from the park? no. it is outside the park in BF
nowhere ... where rents cannot possibly be high.
while they are the only fast food place there, that
is still not a monopoly because of the idea of
contestability [if they were making undue profits
then someone else would open up a restuarant].
so the real explanation is costs. it turns out you
basically have to run a dorm for your crew to have
them live in BF nowhere. --psb
\- BTW, there is an interesting discussion in
Kwoka & White: The antitrust revolution:
economics, competition, and policy
ok tnx, --psb
\_ This is a troll... I was on the I-5 over the weekend and it was
almost always more expensive on the 5 than in Berkeley.
Berkeley ~ $1.45; I saw up to $1.89 on the 5.
\_ Maybe not: http://csua.org/u/476
\_ Collusion. Why does everyone ignore the obvious? |
