Hi all,
  A couple of people wrote to me saying their Anti Virus software
reported that the "learning" directory of the java code is infected
with a worm,  W32.Sircam.Worm@mm to be precise.
Symantec's description of the worm is here
http://www.symantec.com/avcenter/venc/data/w32.sircam.worm@mm.html.

As far as I know this is not true and the code on the site is clean
(but see below) . This is what I did to track down any infestation

1.I have Norton Anti Virus on my Windows system (I do most of my
development on Linux) and a full system scan did not reveal this worm.

2.I downloaded the zip file from the AIMA site and ran a scan on it.
Still "No Infection found".


3.I then visually inspected the code. Since the zip file contains
only, txt, xml, java and class files (and no executable files) I am
not able to make out how the code could be infected. (the SYmantec
description seems to indicate that the worm travels via email with an
executable attachment being the carrier.)

4.I uploaded the  zip file from the aima site as an attachment to an
email using a yahoo account(Yahoo scans all attachments for
viruses/worms ) and yahoo reported an "all clear " as well.

5.I ran the symantec  worm removing
tool(http://securityresponse.symantec.com/avcenter/venc/data/w32.sircam.worm@mm.\
removal.tool.html)
which specifically checks for this worm and found nothing , on the
code on my development machine and the code on the AIMA site

At this point I think one of the following is happening (a) an
antivirus product is delivering a false positive (b)The Symantec
Norton Anti Virus product is broken and does not detect an infection
or (c) the zip file is being infected after being downloaded onto an
infected PC.The fact that aima.zip is often the first zip file
encountered in a search may have something to do with this? (d)
Smething really weird is happening and I have no clue what.



As far as I can make out, the code on my machine and that on the aima
site are not (repeat NOT) infected. However I am not an expert on
security and I could be wrong. I request anyone encountering this
phenomenon to kindly mail me with details of

(a)what antivirus software they are using
(b) the exact message the AV tool pops up
(c) the infected file's name if the tool points to a particular file
as being infected.

A generic report of " your code is infected. Please help" is next to
useless.

You may want to try run the worm removal tool and re download the zip
file from the website. If your AV tool reports the zip file as
infected  *as you download*, please write to *me* ( and NOT to this
forum) at magesmail@.... Any help much appreciated.

Ravi

Hi all,

<update>
I have completed checking the aima java archive with norton, mcAffee
and PC Cillin.All 3 products report that the archive is clean. It
seems that the archive is getting infected AFTER download onto an
infected network.(both reports came from the same university)

The worm's description at
http://www.symantec.com/avcenter/venc/data/w32.sircam.worm@mm.html
seems to indicate that the worm spreads through email (executable)
attachments.

Since the archive does not contain any kind of binary file(except
.class files) worm infection is very unlikely. In the next upload, I
will  include an MD5 hash so people can check if the archive has been
tampered with.

Conclusion : The aima.zip file  on the AIMA site is clean.
If I get any data to indicate the contrary, I'll post it here.

</update>

Ravi

Hello friends,
     I have been going through the chapter of Rapid Software
Development. When I came across Extreme Programming what puzzled me
was what can be the disadvantages of using story cards in XP. I
searched for the same in google but hardly found anything. So can
someone tell me if they are any disadvantages of using a story card.
Thanx in advance
Pavan.

Pavan,
This question is irrelevant in  *this* forum, which is about the AIMA
book, written by Dr Norvig and Dr. Russell. You may want to try the
extreme programming group on yahoo, where you'll get  answers to your
questions.
Thanks,
Ravi

Hi all!

What do you belive will be the most usefull area for AI. Perhaps in the
mediclal area, to cure and take care of the sick and elderly, or in
crime prevention?

i just started to read the book and i hope that my time will be well
spent.

AI is going to drive research in biology in the future. Infact, i may
even go to the extent of saying immediate future.

Could you explain it a little more. Which biology research is related with AI.
I'm very interested in. Some links ?

Most computational problems in biology are being solved using AI
techniques. I give a few links below,
1. Evaluation of Gene Protein Prediction Programs
http://www.cs.jhu.edu/~salzberg/guigo.ps

2. Locating Protein Coding Regions in Human DNA using a Decision Tree
Algorithm
http://www.cs.jhu.edu/~salzberg/exons.ps.gz

3. Genetic operators for the DNA fragment-assembly problem
ftp://mammoth.cs.unm.edu/pub/forrest/dna-fragment-94.ps.gz

4. Machine Learning in Molecular Biology Sequence Analysis
http://citeseer.ist.psu.edu/chan91machine.html

There are several such things going on, the field is basically called
computational biology or bioinformatics. One link that is of quite an
interest would be,

Hi Mattias,

i wonder if AI can be used to translate all language in this world, still it's a
lot works to do,
but for example like English -> French, but in an everyday language...

just an idea, because in my country we have 580 dialect,
so by translate one language into another,
it will surely help people to understand others better :)

it can be used in an neural networks system too...

I have a problem related to planning. Can anyone take a look and
give any suggestion?

The chapter 11 and 12 in the AIMA boook talks about the planning,
but it doesn't talk much about STRPS-like schemas. I am reading a
paper by Daniel S. Weld, "An Introduction to Least Commitment
Planning", which talks more about the extensions such as universal
quantification, conditional effects, etc.

The Universally quantified conditional effects allow the
specification of objects such as briefcases, where moving the
briefcase causes all objects inside to move as well.

If we write out the action, it will look like.
Action(Move(b,from, to),
PRECOND: at(b, from) and (from NOTEQUAL to)
effect: (at(b, to) and NOT at(b, from) and
    for all x, when in(x,b): NOT at(x, from) and at(x, to).

Assuming I have a initial state that my driverlicense is in the
wallet, which is in the briefcase. And the briefcase is in New York.
That is:

at(briefcase, NY) and at(wallet, NY) and at(DriverLicense, NY) and in
(wallet, briefcase) and in(DriverLicense, wallet).

If we apply the action move(briefcase, NY, FL), we can get :
at(briefcase, FL) and at(wallet, FL) and at(DriverLicense, NY) and in
(wallet, briefcase) and in(DriverLicense, wallet).

The DriverLicense is still in NY. How can I write the action so
DriverLicense will move to FL too? My thought is that we should
recursively change the state in the EFFECT clause for all sub-
clause. Is there any syntax support for this kind of problem?

Thanks,
JT

I could presumably slug through getting it to work, but wondering if
anyone else has tried openmcl.  It seems to be pretty solid, but not
behaving too well in trying to get started.

This seems wrong to me, but I just wanted to make sure. Fourth
paragraph on page 633 of the second edition it says

"It is irrational to play a strongly dominated strategy, and
irrational not to play a dominant strategy if one exists."

should probably say something like

"It is rational to play a strongly dominated strategy, and irrational
not to play a dominant strategy if one exists."

JimDavies
http://www.jimdavies.org/

You just misread it - dominated vs. dominant

Strongly dominated strategy = a strategy that is
strongly dominated by another, a.k.a one that sucks.
Therefore it is irrational to play a strongly
dominated strategy.

dear all ,
I need some help

I'd like to ask if there is any possible way to get the book
Exercises' solutions

is there any link or resource , I can make use of ??

thanks

Hi,
  I believe Dr Norvig has stated on this list that the manual is
available only for Instructors. If you are one, you should be able to
make use of the information at
http://aima.cs.berkeley.edu/instructors.html to order a copy.

Just stating what I know. If someone knows differently, do correct me.
I personally have not felt the lack of an Instructors Manual. Most of
the fun is (imho) in trying to solve the problems on one's own.

There seem to be about three files that were updated today.  A number
of directories in the updated Lisp code are empty, e.g., search/ and
learning/.  A comment on the site reads: "The updates will be
incorporated soon into the standard AIMA Lisp code."

So at the moment, anyone who downloads the code.tar.gz file will get
an incomplete collection of code.  The previous, full version, is not
available.

So the new file should NOT be used to replace your old AIMA Lisp code
collection.  It would have to be merged manually.  I'll wait, thanks,
since I'm using an older version of Allegro.

I'm teaching decision making now, and the students have this question
about information value that I'm having trouble answering.

RN2 p602 says that information has value to the extent that it is
likely to cause a chagne of plan and to the extent that the new plan
will be significantly better than the old plan. Are these independent?

I'm trying to come up with a intuitive example of this, and I'm having
trouble coming up with a situation in which the information is
unlikely to affect your decision, but the information might result in
a significantly better decision.

I came up with the idea of buying a DVD player, choosing between going
to get it at best buy (A) and circuit city (B). The information in
question is the exact prices at these stores. The agent knows the
price ranges.

Situation 1:
A: $10-80
B: $15-98

In this case, it's likely to affect your decision and you could save a
lot of money because of it. The information is worth most in this case.

Situation 2:
A: $48-51
B: $49-53

It's likely to affect your decision, but the difference is not big, so
the decision doesn't really matter, so the information is not worth as
much.

Situation 3:
A: $30-50
B: $48-60

Unlikely to affect decision, because A is so much more likely to be
cheaper, AND the price ranges are so close that you don't save much
money. Information worth the least in this case.

Situation 4:
A: ??
B: ??

I want an example in which it's unlilkely to affect your decision but
the decision could be significantly better given the information. I
was thinking
A: $10-51
B: $68-98
but it seems with such a little overlap it's hard to say that the
change in decision will be important. How can it not affect your
decision and also result in a significantly better outcome?

Or am I thinking about this in the wrong way?
